Need help with simple physics questions!
Energy of a photon is
Energy of a photon = h* c/
As we know, speed of light= frequency * wavelength
Hence ,
Energy can also be represented as = h* f
Where h= planck's constant
Correct Answer: option A and C

Can someone help with my physics question pkease with explanation? The max characteristic x-ray photon energy comes from the capture of a free electron into a K shell vacancy. What is this photon energy in keV for tungsten, assuming the free electron has no initial kinetic energy?
I need help with these 2 questions.
thank you
