Question

the speed of light in 992 is 3x10 m/s-
if the refractive index of glass is
then find the time to kos by
light to travel a
distance of 2000
in glass
Ug = 15​

Answer 1

Answer:

$\huge\purple {\mathfrak{Bonjour Mate!}}$

Refractive Index = Speed of light in vaccum/s

1.5 = 3×10^8/speed of light in glass

Speed of light in glass

= (3×10^8)/1.5

= 2× 10^8 m/s
