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

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
