A photon has an energy E and wavelength l before scattering from a free electron. After scattering through a 135° angle, the photon’s wavelength has increased by 10.0%. Find the initial wavelength and energy of the photon.
An x-ray photon with wavelength 15.0 pm is scattered at 84.0° by an electron. What is the wavelength of the
scattered photon?
When a photon has an energy of E and a wavelength of l prior to scattering from a free electron, determine the photon's a) initial wavelength and b) initial energy. The wavelength has risen by 10% after scattering at a 135 degree angle.
