Question

Calculate the refrative index of water with respect to glass and refrative index of glass with respect to water if speed of light in water and glass is 22×10^8m/s and 2×10^8 m/s

Answer 1

Please find attached answer

Answer 2

refractive index of water with glass=speed of light in water/speed of light in glass

$22 \times 10 {}^{8} \div 2 \times 10 {}^{8}$
=11

refractive index of glass with water=


reciprocal of refractive index of water with glass
=1÷11
=0.09
