Question

The optical path of a day light of given wavelength travelling a distance x cm through a medium having refractive index 1.25 determine the value of x.

Answer 1

Answer:

Given: The distance travelled by wavelength in flint glass is 3cm

The refractive index of Flint glass is 1.6

The refractive index of another medium is 1.25

1.25

1.6

=

3

x

Therefore x=

25

3×1.6

x=

25

96

x=3.84cm
