A proton, a neutron, an electron and an α-particle have same energy. Then, their de-Broglie wavelengths compare as:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
We know that the relation between 
and K is given by
Here, for the given value of energy 
is a constant.
Thus, 
Since, 
, hence 
As, 
, therefore 
As, 
, therefore 
Hence,
