Question 16 (1 point)

Light travels through a material at a speed of 4.3 x 108 m/s. What is the index of

refraction for the material?

Your Answer:

Answer

units

Answer 1

η = 0.7

Step-by-step explanation:

The refractive index of the material can be calculated by using the following formula:

`\eta = (c)/(v)\\`

where,

η = refractive index of the material = ?

c = speedof light in vaccuum = 3 x 10⁸ m/s

v = speed of light in this material = 4.3 x 10⁸ m/s

Therefore,

`\eta = (3\ x\ 10^8\ m/s)/(4.3\ x\ 10^8\ m/s)`

η = 0.7
