Formulas

Question 1

What does the letters in N=C/V mean?

Answer 1

N = Index of refraction
V = Speed of light in a substance
C = Speed of light in a vacuum (3 X 10 8 m/s)
(used to find the index of refraction)

Question 2

What does C=3.0 x 10 8 m/s mean?

Answer 2

The speed of light in a vacuum

Question 3

What does n1 sinθ1 = n2 sinθ2 mean?

Answer 3

The index of refraction

Question 4

What does the letters 1/f = 1/di + 1/do mean?

Answer 4

F is the focal length
Do is the distance from the object
Di is the distance from the lens to the in focus projected image

Question 5

What does M=Hi/Ho=-Di/Do mean?

Answer 5

Used to find the magnification
