Question

Part 1: What does this diagram indicate about the indexes of refraction of the three mediums?

**image attached inside!**

A. The index for Medium 2 is larger than the index for Medium 1.

B. The index for Medium 2 is equal to the index for Medium 3.

C. The index for Medium 2 is equal to the index for Medium 1.

D. The index for Medium 3 is larger than the index for Medium 2.

Part 2: *same diagram!* What does this diagram indicate about the speed of light in the three media?


A. Light travels faster in Medium 3 than in Medium 2.

B. Light has the same speed in Medium 3 and Medium 2.

C. Light travels faster in Medium 2 than in Medium 1.

D. Light has the same speed in Medium 2 and Medium 1.

Answer 1

no not sure of this

Answer 2

actually i dont take physics

Answer 3

ohh okay, thank you though!

Answer 4

im taking ap chem next year

Answer 5

ooh okie!

Answer 6

With greater refraction the light will have to travel farther and will take more time to reach a given destination. The higher the refractive index, the lower the speed at which light travels.

Answer 7

so for part 1, is choice D the accurate answer? or would it be choice A? :/ they wouldn't be equal right? I am between those two choice (A and D) now :/

Answer 8

@perl? :)

Answer 9

and i have no idea for part 2 :(

Answer 10

i think thats right, just making sure

Answer 11

okie yay! what about the second part? :/ confused :(

Answer 12

so for part 1 it should be choice D? :)

Answer 13

when light moves from a material in which its speed is higher to a material in which its speed is lower, the ray is bent toward the normal

Answer 14

so from medium n1 to n2, the ray is bending away from the normal, therefore the speed of light is faster in n2 than in n1

Answer 15

okay! so for part 1, it is D ? and for part 2, it would be choice C?

Answer 16

88? :/

Answer 17

yes i agree with your answers 1. D , 3. C

Answer 18

since it is moving away from the normal in medium 2

Answer 19

yay! thank you very much @perl :)

Answer 20

So to summarize.

When light moves from a material in which its speed is higher to a material in which its speed is lower, the ray is bent toward the normal

When light moves from a material in which its speed is lower to a material in which its speed is higher, the ray is bent away from the normal

The slower the light moves through a medium, the higher the index of refraction.
glass has n = 1.66
diamond has 2.419

Answer 21

yes:)

*sorry, got booted off haha :P
