A student measures the speed of yellow light in water to be 2.00x10^8

NOTE: The given question is incomplete.

The complete question is given below.

A student measures the speed of yellow light in water to be 2.00 x 10⁸ m/s. Calculate the speed of light in air.

Solution:

Speed of yellow light in water (v) = 2.00 x 10⁸ m/s

Refractive Index of water with respect to air (μ) = 4/3

Refractive Index = Speed of yellow light in air / Speed of yellow light in water

Or, The speed of yellow light in air = Refractive Index * Speed of yellow light in water

or, = (4/3) * 2.00 x 10⁸ m/s

or, = 2.67 * 10⁸ m/s ≈ 3.0 * 10⁸ m/s

Hence, the required speed of yellow light in the air will be 3.0 * 10⁸ m/s.
