Question

If the absolute refractive indeices of water, benzene, and saphire are 1.33,1.50and 1.77 respectively, then which medium has maximum relative refractive index ?

Page 44 Chapter - 2.Reflection and Refraction

Answer 1

RI of refractive index of water w.r.t diamond = 1.33/2.42=0.54

RI of refractive index of diamond w.r.t benzene =2.42/1.50=1.6133

Diamond{water}>diamond {benzene}

Answer 2

Hello Dear,

◆ Answer -

Relative refractive index of saphire wrt water will be maximum

◆ Explaination -

# Given -

nw = 1.33

nb = 1.5

ns = 1.77

# Solution -

Relative refractive index of water wrt benzene is -

nwb = nw/nb

nwb = 1.33/1.5

nwb = 0.8867

Relative refractive index of water wrt saphire is -

nws = nw/ns

nws = 1.33/1.77

nws = 0.7514

Relative refractive index of benzene wrt water is -

nbw = nb/nw

nbw = 1.5/1.33

nbw = 1.128

Relative refractive index of benzene wrt saphire is -

nbs = nb/ns

nbs = 1.5/1.77

nbs = 0.8474

Relative refractive index of saphire wrt benzene is -

nsb = ns/nb

nsb = 1.77/1.5

nsb = 1.18

Relative refractive index of saphire wrt water is -

nsw = ns/nw

nsw = 1.77/1.33

nsw = 1.33

Hence, relative refractive index of saphire wrt water will be maximum.

Thanks dear...
