Answer:
η = 1.31
Explanation:
The formula for the refractive index of from air to some other medium is given by the following formula:
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:
<u>η = 1.31</u>
