Question

Light travels at 3.0 × 108 m/s in a vacuum. use the index of refraction for water to determine the speed of light in water. round your answer to the nearest tenth. × 108 m/s

Answer 1

Answer:

the answer is 2.3. I just answered this question and got it right.

Explanation:

Answer 2

The phenomenon bending of a wave as it crosses from one medium to another is said to be refraction. The speeds of light in the water will be 2.25×10⁸ m/sec.

What is the definition of refraction?

The phenomenon bending of a wave as it crosses from one medium to another is said to be refraction. The difference in density is the cause of the bending.

Refraction is a term that is used to describe the phenomenon of refraction."The change in direction of a wave traveling through one medium to another is known as refraction."

The following data are given in the problem;

C is the Speed of light in a vacuum =3×10⁸ m/sec.

n is an index of refraction for water = 1.333

v is the speed of light in the water=?

The index of refraction is the ratio of the speed of light in a vacuum to the speed of light in water. By the formula of the index of refraction.

$n=\dfrac{c}{v}$

$V=\dfrac{c}{n}$

$V=\dfrac{3\times10^8}{1.333}$

$V=2.25\times 10^8 m/s$

Hence the speed of light in the water will be 2.25×10⁸ m/sec.
