Acoating of film n=1.33 on glass slabs (n=1.6) is 8.3×10e−5 cm thick. if white light is incident normally, which visible wavelengths are missing in the reflected light?

the missing wavelengths would be those that give length of

Explanation:

Data:

Let the coating of the film be n = 1.33 on glass

The refractive index = 1.6

Thickness of the slab = 8.3 × 10⁻⁵ cm

Therefore, the angles are all determined from the normal

This gives:

The relationship, known as Snell's law, can be used to evaluate the missing angles in the wavelength region.

yup its correct its: c) b b

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
