Question

Speed of light in air is 3 x 10^8 m/s
Speed of light in water is 2.26 x 10^8 m/s.
Find the refractive index of water.​

Answer 1

Answer:

3 x 10⁸/2.26 x 10⁸

= 3/2.26= 1.32743363= 1.33 is your answer please make me brainliest.

Answer 2

Answer:

The correct answer is : 1.33

Step-by-step explanation:

So, to find the refractive index of water, we need to divide the speed of light in a vacuum (which is approximately 3 x 10^8 m/s) by the  speed of light in water (which is 2.26 x 10^8 m/s):

$Refractiveindexwater = speed of light in a vacuum / speed of light in water$

= (3 x 10^8 m/s) / (2.26 x 10^8 m/s)

= 1.33

Therefore, the refractive index of water is 1.33. This means that when light passes through water, its speed is reduced by a factor of 1.33 compared to its speed in a vacuum. The refractive index of water is higher than that of air (which is approximately 1.0003), which means that light is more strongly refracted when it passes from air to water or vice versa. This has important implications for the behavior of light in optical devices such as lenses and prisms.
