Hey ...
Given Refractive Index = 3/2
∵ Refractive Index = Speed of the light in air/Speed of the light in glass.
3/2 = 3 × 10⁸/Speed of the light in glass.
∴ Speed of the light in glass = 2 × 10⁸ m/s.
Thickness of the glass plane =4mm
=0.4 cm
=0.004 m
=4×10⁻³m
Time taken =(4 × 10⁻³)/(3×10⁸)
=1.3×10⁻¹¹ s.
