Question

The speed of light in glass is 2×10^8 m/s. what is the refractive index of glass?​

Answer 1

Answer:

refractive index is 1.5

Answer 2

Answer:

Hello mate✌✌✌

Given,

• n = ?
• c = 3 × 10^8 m/s
• v = 2 × 10^8 m/s

Now,

$n = \frac{c}{v} \\ n = \frac{3 \times {10}^{8} }{2 \times {10}^{8} } \\ n = 1.5$

Hope it helps✌✌✌
