Question

What is the de broglie wavelength of 10 Mev electron

Answer 1

The wave length is
`3.885*10^(-13)\ m`

Step-by-step explanation:

Given that,

Energy = 10 Mev

We need to calculate the wavelength

Using formula of debroglie wave length

`\lambda=(h)/(√(2mE))`

Where, h = Planck constant

E = energy

m = mass

Put the value into the formula

`\lambda =\frac{6.634*10^(-34)}{\sqrt{2*9.11*10^(-31)*10*10^(6)*1.6*10^(-19)}}`

`\lambda=3.885*10^(-13)\ m`

Hence, The wave length is
`3.885*10^(-13)\ m`
