NEET Physics de Broglie Wavelength MCQ Question
Type: MCQ-numerical-Easy-Class 12
What is the de Broglie wavelength of a proton (mass = 1.67 × 10^-27 kg) moving with a speed of 2.0 × 10^6 m/s?
A
98 × 10^-14 m
B
31 × 10^-11 m
C
98 × 10^-10 m
D
31 × 10^-14 m
Correct Answer
Option D
Detailed Explanation
The de Broglie wavelength is calculated using λ = h/p, where p = mv. For a proton, λ = (6.63 × 10^-34 J s) / (1.67 × 10^-27 kg × 2.0 × 10^6 m/s) = 3.31 × 10^-14 m.
