Explain why a golf ball and a basketball can have the same momentum when both of them are moving, and then why an x-ray photon and an infrared photon can't have the same momentum. be specific; no equations or math. b) x-ray photons hit the surface of a block of aluminum (work function 4.08 ev) and knock off electrons with a maximum speed of 2.87x106 m/s. calculate the photons' wavelength c) other photons now strike the aluminum block, but no electrons are ejected. how do these photons differ from the photons from part (b)? explain without equations or further calculation.
