Question

the refractive index of diamond is 2.42 and that of glass is 1.52 if the velocity of light is 2*10^8 m/s then calculate the velocity of light in diamond and vacuum

Answer 1

Answer:

here u go

plz mark me as brainliest

Answer 2

$\huge\underline{\overline{\mid{\bold{\red{ANSWER-}}\mid}}}$

speed of light in glass=c/1.51

speed of light in diamomd=c/2.42

relative speed required=c/1.51-c/2.424

=0.25c
