Question: If unpolarized light passes through a polarizer, what is the intensity of the transmitted light?

Options:

Correct Answer: Half of the original intensity

Solution:

According to Malus\'s law, the intensity of transmitted light is half of the original intensity when unpolarized light passes through a polarizer.

If unpolarized light passes through a polarizer, what is the intensity of the transmitted light?

If unpolarized light passes through a polarizer, what is the intensity of the transmitted light?

Step 1: Understand that unpolarized light consists of waves vibrating in many directions.
Step 2: Know that a polarizer is a special filter that only allows light waves vibrating in a specific direction to pass through.
Step 3: When unpolarized light hits the polarizer, it gets filtered.
Step 4: According to Malus's law, the intensity of the light that comes out of the polarizer is half of the intensity of the incoming unpolarized light.
Step 5: Therefore, if the original intensity of the unpolarized light is 'I', the transmitted intensity will be 'I/2'.

Malus's Law – Malus's law states that when unpolarized light passes through a polarizer, the intensity of the transmitted light is given by I = I0/2, where I0 is the intensity of the unpolarized light.
