Question

Index of a dense flint glass is 1.65 and 4 alcohol it is 1.36 with respect to air and the refractive index of

Answer 1

The refractive index of dense flint glass with respect to air is

n21 = n2/ n1 = n2 =1.65 (because n1 = 1.00)

The refractive index of alcohol, with respect to air,

n31 = n3/ n1 = n3 =1.36 (because n1 = 1.00)

The refractive index of flint glass, with respect to alcohol is,

n23 = n2/ n3 = 1.65/1.36 = 1.21

Thus, the refractive index of dense flint glass with respect to alcohol is 1.21
