Question

refractive index of glass is 4\3.then find speed of light in glass​

Answer 1

Answer:

The absolute refractive indices of glass and water are 4/3 and 3/2 respectively. If the speed of light in glass is 2 * 10^8 m/

Answer 2

n=s.o.l in air/s.o.l in medium

n=4/3

s.o.l in glass=?

4/3= 2×10power8 m/s

=3×10power8 m/s
