NEET Chemistry Quantum Mechanical Model Assertion Reason Question
Assertion (A): The photoelectric effect can be observed even with low intensity yellow light on potassium metal.
Reason (R): The energy of emitted photoelectrons depends on the frequency of incident light, not its intensity.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The photoelectric effect depends on the frequency of light, and yellow light has a frequency above the threshold frequency for potassium. Hence, both assertions are true, and the reason correctly explains the assertion.
