PHY 104 Photo Electric Emission Objective Question

Question

What does the wave theory predict about the relationship between photoelectric current and light intensity?
Options
A Current is independent of light intensity.
B Current increases proportionally with light intensity.
Correct Answer
C Current only flows if intensity is above a certain threshold.
D Current decreases with increasing light intensity.
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to the graph on page 2 illustrating wave theory predictions, the 'Icurrent' (current) increases linearly with 'Ilight intensity'.

Hint

Refer to the top-left graph on page 2 under 'Photoelectric Effect' and 'wave theory predicts'.
