Question

Write one or two sentences to define refraction and to describe a situation that demonstrates this wave interaction.

Answer 1

- bending of light as the result of entering a new medium with a different substance
- change in angle is caused by the difference in refractive index of the two substances

Answer 2

Refraction is the bending of light that occurs as a result of when it enters a new medium but with a different substance. Also, there is a change in angle because of the difference of 2 substances in a refractice index.

Answer 3

Is this alright

Answer 4

keep in mind if your phrasing is very close to mine, my writing will come up in the plagiarism checker

Answer 5

When a contrasting element flows into a new component, light will bend. This is refraction.

Answer 6

is this alright

Answer 7

that's a little bit off, "contrasting element flows into a new component" is a bit strange and doesn't really describe what light is

Answer 8

my tip for paraphrasing is to read something slowly and carefully, then cover it up and try to re-write it (without looking), it's less likely to result in accidental plagiarism that way

Answer 9

A bent light made of a contrasting substance which enters into a new type of medium

Answer 10

this, maybe?

Answer 11

the light isn't the thing that's made of the "contrasting substance" it's the medium

Answer 12

oh im sorry, this is actually what I am struggling with rn

Answer 13

- light enters medium
- new medium is made of something different, therefore it has different index of refraction
- this causes bending and change of angle

^ try to combine these pieces of information in your own words

Answer 14

writing isn't really my area of expertise, I'm not sure how to advise you on this :S

Answer 15

Refraction first starts when light enters into a medium. This medium is new because it is not made of up of the same element as before. Because this is a new medium, there is also an index of refraction which is not the same. As a result of this the light bends and the angle is changed.

Answer 16

Tried my best :(

Answer 17

*causing refraction** at the end

Answer 18

well done

keep in mind if you post something here and then submit the exact copy it will also come up in the plagiarism checker ;_;

it's best to use my writing as a reference and try to keep a separate word document with your re-written responses

Answer 19

Yes I think that is what I am going to do. I have to take this really serious and I dont have much work left, but whatever is i have to watch very carefully what I am writing. Is it alright if I check the responses over with you like I did her so you can tell me if I reworded it correctly?

Answer 20

here*

Answer 21

sure

Answer 22

I have about an hour left before I have an appointment for something

Answer 23

Okay sounds good

Answer 24

our friend beats a drum across the room from you. How does the drum make a sound? How does the energy of the sound reach you? Why don't you feel a push of air when you hear the sound? Write three or four sentences to state your answers.

Answer 25

Your*

Answer 26

going off the top of my head, when you hit the drum you produce vibrations on its surface which carry the energy into the air around it, causing sound waves that will propagate and hit your eardrum, which your body interprets as sound

not sure about the second part, I think it's because the wave transmits energy not physical matter, thus not causing actual air to move and hit the ear

Answer 27

**When**The drum makes this sound there are vibrations that are made which result in the carrying of air , which then results in waves that clash with your eardrum, which finally results in your ears thinking of this as sound that the drum makes. I think you do not feel the push of aiir when you hear the sound because the wave carries energy. It does not transmit actually phsyical matter. As a result of this, there is no push of air that you hear when this sound is made.

Answer 28

edited version

Answer 29

gotta make sure it makes sense grammatically (check the first sentence again)

also you don't need to say "I think" in the final answer, the grader will assume this is your own thinking haha

Answer 30

When the drum makes a sound, there are vibrations that are made which result in the carrying of air. This then results in waves that clash with your eardrum, which then results in your ears thinking of this as sound that the drum makes. You do not feel the push of air when you hear the sound because the wave carries energy. It does not transmit actual phsyical matter. Because of this, there is no push of air that you hear when this sound is made.

Answer 31

good
