Reflection and Refraction

Question 0

What do each of the variables in Snell’s Law equation stand for?

Answer 0

N= index of refraction
C= speed of light
V= speed of light in medium

Question 1

What is the equation for finding the index of refraction?

Answer 1

N= C/V

Question 2

What is the equation for finding the angle of refraction?

Answer 2

Ni•sin•€i=nr•sin•€r

Question 3

What do each of the variables in the equation for finding the angle of refraction stand for?

Answer 3

Ni= index of refraction in angle of incidence medium

Nr= index of refraction in angle of refraction medium

Sin= ?

€i= angle of incidence

€r= angle of refraction

Question 4

What qualities should one consider when classifying an image?

Answer 4

1. Virtual or real
2. Erect or inverted
3. Same size, smaller, or larger

If the image cannot be seen, it would be classified as no image.

Question 5

What is the mirror and lens equation?

Answer 5

1/f= 1/do + 1/di

Question 6

What is the magnification equation?

Answer 6

Hi/Ho= -(Di/Do)
