NEET 2014 Physics de-Broglie Wavelength MCQ Question
Type: MCQ-conceptual-Medium-Class 12
If the kinetic energy of the particle is increased to 16 times its previous value, the percentage change in the de-Broglie wavelength of the particle is
A
25 %
B
75 %
C
60 %
D
50 %
Correct Answer
Option B
Detailed Explanation
The de-Broglie wavelength λ is inversely proportional to the square root of kinetic energy (KE). If KE is increased 16 times, λ becomes 1/ of its original value, leading to a 75% decrease.
