Question

Light enters from air to glass having refractive index 1.50.What is the speed of light in the glass? The speed of light in vacuum is 3*10

Answer 1

Answer:

3×10^8/1.5

=2×10^8 ans

Answer 2

$\mathfrak{\huge{\pink{\underline{\underline{Answer:-}}}}}$

♦Refractive Index = Speed of light in vaccum/speed of light in medium

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
