A)2.43 pm
B)4.85 pm
C)There is no maximum value.
D)The wavelength of the x-ray photons doesn't increase.It decreases.

Quizplus · Accepted Answer

The maximum increase in wavelength during Compton scattering can be calculated using the formula Δλ = (h/mc)(1 - cosθ), where h is Planck's constant, m is the electron mass, c is the speed of light, and θ is the angle of scattering. At 180 degrees (backscattering), the maximum possible increase in wavelength is given by Δλmax = 2(h/mc) = 4.85 pm. Therefore, option B is the correct answer.
