Question

The speed of light in air is 3 x 108 m/s. The speed of light in ice is 2.29 x 108 m/s. What is the refractive index from air to ice?

Answer 1

η = 1.31

Step-by-step explanation:

The formula for the refractive index of from air to some other medium is given by the following formula:

`\eta = (c)/(v)\\`

where,

η = refractive index = ?

c = speed of light in air = 3 x 10⁸ m/s

v = speed of light in ice = 2.29 x 10⁸ m/s

Therefore, using these values in the equation we get:

`\eta = (3\ x\ 10^8\ m/s)/(2.29\ x\ 10^8\ m/s) \\`

η = 1.31
