Log 6 - Index of Refraction

Question 1

What 3 things that may happen when a ray of light travels from one material to another.

Answer 1

1. Absorbtion
2. Reflection
3. Refraction

Question 2

Absorbtion is when light is absorbed when it _______ a material and does not _______

Answer 2

enters
exit

Question 3

Reflection is when a ray of light hits a smooth surface it will ________ at the same angle _______ from the surface.

Answer 3

bounce
away

Question 4

Refraction is if a ray of light strikes a new transparent material at ______ degree angle it will slow down but pass straight through. Ex. Light passing from air to water.

Answer 4

90 degrees

Question 5

Law of Reflection =

Answer 5

angle of incidence = angle of reflection

Question 6

What does the d, i, and i’ mean in
d=i’ -i

Answer 6

d= angle of deviation
i' = angle of incidence
i= angle of refraction
