Question

Calculate the speed of light in a medium who critical angel is 50 and velocity of light in air is 3*10 raise to 8 m/s solved numerical step by step

Answer 1

n=1/sinc

n=1/sin(50)

n=1.31

n=speed of light in air/speed of light in medium

1.31=3*10^8/x

x=3*10^8/1.31

x=229007633.6m/s

x=2.3*10^8
