Answer:

[tex]\Delta \lambda=4.94\times 10^{-13}\ m[/tex]

Explanation:

It is given that,

X-rays are scattered from a target at an angle of, [tex]\theta=37.2^{\circ}[/tex]

We need to find the wavelength shift of the scattered x-rays. The shift in wavelength is given by :

[tex]\Delta \lambda=\dfrac{h}{mc}(1-cos\ \theta)[/tex]

h is the Planck's constant

m is the mass of electron

c is the speed of light

[tex]\Delta \lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-31}\times 3\times 10^8}(1-cos(37.2))[/tex]

[tex]\Delta \lambda=4.94\times 10^{-13}\ m[/tex]

So, the wavelength shift of the scattered x- rays is [tex]4.94\times 10^{-13}\ m[/tex]. Hence, this is the required solution.
