Question: If the intensity of light is doubled, what happens to the number of photoelectrons emitted?

Options:

Correct Answer: Doubles

Solution:

Doubling the intensity of light doubles the number of photons, thus doubling the number of photoelectrons emitted.

If the intensity of light is doubled, what happens to the number of photoelectrons emitted?

If the intensity of light is doubled, what happens to the number of photoelectrons emitted?

Step 1: Understand that light is made up of tiny particles called photons.
Step 2: Know that the intensity of light refers to how much light energy is present.
Step 3: Realize that doubling the intensity means there are now twice as many photons hitting a surface.
Step 4: Remember that each photon can cause the emission of one photoelectron when it hits a material.
Step 5: Conclude that if there are twice as many photons, then there will be twice as many photoelectrons emitted.

Photoelectric Effect – The phenomenon where electrons are emitted from a material when it is exposed to light, depending on the light's intensity and frequency.
Photon Theory – Light is composed of photons, and the intensity of light is related to the number of photons hitting a surface.
