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.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
