STANDARD Physics de-Broglie Wavelength MCQ Question
Type: MCQ-numerical-Medium
The de-Broglie wavelength of a particle with mass 1 gm and velocity 100 m/sec is
A
6.63 × 10⁻³³ m
B
6.63 × 10⁻³⁴ m
C
6.63 × 10⁻³⁵ m
D
6.65 × 10⁻³⁵ m
Correct Answer
Option A
Detailed Explanation
The de-Broglie wavelength λ is given by λ = h/mv. Substituting the values, λ = 6.63 × 10⁻³⁴ / (10⁻³ × 100) = 6.63 × 10⁻³³ m.
