Question

Calculate the refractive index of the material of a glass slab. given that the speed of light through the glass slab is 2×10^8 m/s and in air is 3×10^8 m/s

Answer 1

Answer:

3/2 or 1.5

3/2 or 1.5 Explanation:

3/2 or 1.5 Explanation:n = c/ v

3/2 or 1.5 Explanation:n = c/ v3 x 10^8 /2 x 10^8

3/2 or 1.5 Explanation:n = c/ v3 x 10^8 /2 x 10^8 = 1.5
