Hello Dear,
◆ Answer -
(A) Saphire relative to water
◆ 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...
