If light is invisible ,how does the surrounding area
become visible​

Answers

Answer 1

Answer:

Reflection, absorption and re-emission.

To clarify, you mentioned light is not visible. Of course that is not true, we can see light. our retinas are sensitive to light within a certain range of frequencies. you may be commenting on the fact that if there is a beam of light in front of me traveling from right to left, I won’t see it. That’s true. If it were a ball I would see it. That is because light strikes the ball, is reflected, absorbed, and re-emitted or some combination of the above, then that light strikes my eye.

As a side note, if the ball were somehow changed by the light which struck it (change of course due to momentum of light impact) then I may not be able to trust that the image I see truly represents the current condition of the ball. But for most balls we can see, this is not the case. If, however, we do go smaller in our attempt to ‘see’ light, we won’t necessarily be able to trust our instinctive intuition. That is informed by the large scale world we observe with our unaided eye. We would have to learn to trust our observations however those observations come. And the observed truth of the very small, the world of quantum physics, is rather different than our unaided perception. It is nevertheless equally valid.

Back to the main point.

If you like to play the semantics game of asking whether you see the ball or see the light, suit yourself. The ball interacts with light, the light interacts with my eye, my eye sends data to my brain for interpretation. I’m fine with either version of ‘seeing’ the ball or ‘seeing’ the light.

Here’s an example to hopefully clarify.

I’m outside on a sunny day, no electric lights around, only sunlight. We all know sunlight is well collimated, one-directional. I’m in my back yard in the shade of my awning. No direct sunlight strikes me or the ball in my hand.

How do I see the ball in my hand?

Direct sunlight strikes a number of objects around me, the ground, my pool, etc. I don’t see any of that light. All of those objects reflect some light. That reflected light leaves the objects at certain limited angles based on the angle of incidence of the sunlight striking that surface. They also absorb some light. They then re-emit the light they absorb. Based on the surface characteristics, this re-emitted light shoots out in all directions away from the surface. They all become sources of multi-directional light nearby, just much lower intensity. Like a bunch of little light bulbs. So the ball I hold (in the awning’s shadow) is lit from a number of sources, just much more dimly than the ground lit by direct sunlight. And so the ball appears darker. It is in the shadow after all.

By the same principle, if the part of Earth you are standing on is in the shadow of the rest of the Earth, i.e. it is nighttime, then you won’t see anything. Unless of course there are other objects around Earth (moon, et al.) that absorb and re-emit light. When the sun, Earth, and moon are lined up so that the sunny side of the moon has a lot of its surface area facing towards Earth (full moon) then there is a lot of reflected and re-emited light striking Earth. Those are nights when it is easier to see by moonlight, which is of course sunlight.

Read this excerpt from Exploring the Titanic.

Alvin could only dive to 6,000 feet. Since the average depth of the deep ocean is about 12,000 feet, the Navy decided to give it a new hull of titanium alloy, a very strong metal that could hold up to huge underwater pressures and allow us to dive to 13,000 feet. By chance, this refitting project was called Project Titanus.

Titanium, Titanus, Titanic – that started me thinking. The Titanic was thought to lie at a depth of just over 12,000 feet.

Based on the excerpt, why does the author include the name of the refitting project?

to explain how Alvin was similar to the Titanic
to show how titanium was found inside the Titanic
to connect Alvin with the author’s search for the Titanic
to describe how Project Titanus was named after the Titanic

Answers

Answer:

C. to connect Alvin with the author’s search for the Titanic

Explanation:

What is theme of Titanic?

The creator in the given portion, utilizes his own insight and afterward utilizes emotion and understanding to recount the narrative of Titanic.

While he makes sense of the amount Alvin could plunge and he gave the subtleties of the sea profundity, he specifies the name of the refitting project so he can interface Alvin with the his quest for the Titanic.

It is displayed all through the story that he was very headed to find Titanic. That is the reason toward the end he likewise demonstrated the significance of the disclosure he made.

"Wandering As A Clouds"

Our lives are but clouds wandering across a sky

Restlessly drifting along with a tempestuous wind

Sometimes billowing puffed up sometimes thinned

Or grey with darkened streaks of lightning flashing by

They speed with no mercy in the jet

stream high above

Or labouring they shed their heavy load upon the soil With cymbals' of crashing thunder

they bubble and boil

Yet with ageless beauty they're looked on with love

Like clouds our lives are full of wandering thoughts

Those times we feel happy or pain or

laugh or we weep

We play and we work and make

appointments we can't keep

Of winning the lottery a cheque ending one and six noughts

And have dreams of wielding power

prestige or of love

But spare a thought for those with

monotonous dread

We all drift through this mortal life

until we are dead

And live in memories and history that

once we were part of

We are those wandering clouds in the

heat of the day

We start out as nothing just a few

gentle wisps that grow Shaped by the wheel of fortune

takes a throw

as fate

Then when our cloud evaporates we simply fade away​

Some people believe that technology will eventually make books unnecessary and that they will no longer exist. Write an essay in which you argue against this idea. ​

Answers

Answer:

Books are more reliable then the internet because books are reviewed before their published and have to go through a variety of steps before being published, on the internet the site could be getting changed every hour and misleading you so I would say books are more reliable.

Explanation:

I can give you a few points to write about since i do not know the requirements for your essay but I will write the points in sentence form so it gives you a few sentences to start with or to give you a start.

- with technology you have to care for your technology but with technology comes people dropping their tech damaging it making people spend masses amount of money on it but if you drop a book let's say in water accidentally you can buy it again for the original price (for instance 6$-20$) or just pay the book back.

- some people have a sensitivity to screens and it can cause headaches and more problems for that person.

- if a book is dropped on the floor it is still in good condition

-people have struggled with technology on math because the website had an error but if they used math books they wouldn't have an error.

- The only reason we have e books now is because the written copies were made first

- some people don't understand technology as well as others

- Technology has code errors and can shut down causing problems

- books teach English, reading, and comprehension skills. If you go on an article you may see a grammar mistake or a misclick from people working on computers. Writing books requires a person to write and focus on what they do.

-Books make reading feel more real and less virtual.

- with books you can see the cover art and summaries people make.

- books are less distracting than technology because you could be on your phone reading and a notification goes off and then you are distracted. With books there are no distractions.
