A vertically polarized light wave of intensity 1000 mW/m2 is coming toward you, out of the screen. After passing through this polarizing filter, the wave's intensity is

The intensity is

Explanation:

From the question we are told that

    The  intensity of the unpolarized light is

Generally the intensity of the light emerging from the polarizer is  mathematically represented as

substituting values

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.

explanation:

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
