Answer:

η = 1.31

Explanation:

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

[tex]\eta = \frac{c}{v}\\[/tex]

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:

[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.29\ x\ 10^8\ m/s} \\[/tex]

η = 1.31
