Question: Q. 1. An
U] [Delhi 2017]
Show Answer
Solution:
Ans. de-Broglie wavelength is given by
Mass of a proton
Charge of proton
Hence, Kinetic energy of a proton when accelerated through a potential
Putting these values in de-Broglie wavelength formula to calculate wave length of proton
Now,
- Mass of an
- Charge of an
Hence, Kinetic energy of an
Putting these values in de-Broglie wavelength formula to calculate wave length of
Hence ratio of
