Question 1

What is the primary observation of the photoelectric effect?

Electrons are emitted regardless of light frequency
Electrons are emitted only when light exceeds a threshold frequency
Electrons are emitted at any intensity of light

💡 Hint: Think about the conditions under which electrons are released.

Question 2

True or False: Increasing the intensity of light increases the kinetic energy of emitted electrons.

True
False

💡 Hint: Recall the definition of kinetic energy in the context of frequency.
