Question

What causes light rays to bend in a new medium?

A. change in velocity
b. change in amplitude
c. change in frequency
d. construcutive interference

Answer 1

which one do you think it is?

Answer 2

idk because i m not good in physics and i dont really have time cause today is my last day for me to get a 80% cause i have a 65 and if i dont make an 80 by tommrow my name is going off my graduation list:(

Answer 3

hey don't you think it is better if you understand this as well

Answer 4

yeah it is but i want to graduate i graduate this saturday

Answer 5

and all i have to do is make a 80

Answer 6

Okay,
well try and understand this,
Light refracts (bends) at an angle when it moves into a new medium. When this happens, it causes the light to change its velocity. The angle through which it bends depends on the density of the mediums, which is described by Snell's Law.

Answer 7

ok so whats the answer then

Answer 8

the answer is in the above paragraph, read it, try to understand it :)

Answer 9

change in velocity?

Answer 10

yes

Answer 11

ok

Answer 12

A ray of light bends upon entering a new medium. What is this phenomenon called?

d. dispersion

Answer 13

the answer to this is also in that paragraph :)

Answer 14

ok lets check

Answer 15

c. refraction

Answer 16

?

Answer 17

yes

Answer 18

ok

Answer 19

Which statement about the spectrum of light that emerges from a prism is true?
