Vertically polarized light with an average intensity of is incident on a polarizer whose transmission axis makes an angle of 30o with respect to the horizontal. What is the average intensity of the light that is transmitted through the polarizer?

Explanation:

Average intensity of incident light I₀ .

intensity of transmitted light

I = I₀ cos²θ

if angle between transmission axis and angle of polarization of incident light be θ

In the given case

θ = 90 - angle the transmission axis makes with horizontal

= 90- 30

= 60°

I = I₀ cos²θ

= I₀ cos²60

=   I₀ /  4

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
