AIPMT PRELIMS 2000 Physics Photoelectric Effect MCQ Question
Type: MCQ-numerical-Hard-Class 12
For given energy, corresponding wavelength will be E = 3.03 × 10⁻¹⁹ Joules (h = 6.6 × 10⁻³⁴ J x sec., C = 3 × 10⁸ m/sec.)
A
65.3 nₘ
B
6.53 nₘ
C
3.4 nₘ
D
653 nₘ
Correct Answer
Option D
Detailed Explanation
Using the formula λ = hc/E, where h is Planck's constant, c is the speed of light, and E is energy, the wavelength is calculated to be 65.3 nₘ.
