Question

If the velocity of light in vacuum is 3 ×10 power 8 ms - 1 and in another medium M is 0.75 × 10 power 8 ms-1 what is the refractive index ​

Answer 1

Answer:

$n = \frac{c}{v} = \frac{3 \times {10}^{8} }{0.75 \times {10}^{8} } = 4$

Answer 2

Answer:

refractive index of medium is(3 * 10^ 8) by ( 0.75 * 10^ 8)

= 4
