Answer:
Explanation:
We know that ,
According to de Broglie hypothesis:
where
= wavelength
ke = kinetic energy
Now, the ratio of kinetic energy of proton to that of alpha particle is 4:1
Therefore,
The ratio of square of wavelength will be 1:4
Hence, ratio of wavelength will be (c) 1:2

Explanation:
what many of do wrong in this question is
we forget to equate
four time of mass of proton is equal to the mass of alpha particle
