Question

The refractive index of a material is 1.52 if the velocity of light in vacuum is 3 into 10 raise to 18 metre per second find the velocity of light in the material

Answer 1

Answer:

velocity of light in material =1.97*10^8

Explanation:

i used the formulae

$u = c \div v$

and then put the values and you will get the answer

thank you
