PHY 104 Photo Electric Emission Objective Question

Question

Which statement accurately describes Einstein's contribution to explaining the Photoelectric Effect, as mentioned in the document?
Options
A He proposed that light is a continuous electromagnetic wave.
B He suggested that light consists of discrete units of energy called photons.
Correct Answer
C He discovered the relationship between light intensity and electron kinetic energy.
D He developed the theory of special relativity to explain electron emission.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 3 states, 'Einstein suggested that light consisted of discrete units of energy, ΔΕ = hf.' The document also clarifies that he received the Nobel Prize for this, not for his theory of relativity.

Hint

Recall Einstein's key hypothesis about the nature of light in the context of this effect.
