What is the momentum of a wavelength= 0.015nm X-ray photon? p= in kg*m/s Please help I am confused. Thank you.
Physics
Photons of energy 12eV are incident on a metal. It is found that current flows from the metal until a stopping potential of 8.0V is applied. If the wavelength of the incident photons is doubled, what is the maximum kinetic energy of the ejected electrons? What is KEmax in eV. ...
Physics Please COULD SOMEONE HELP ME ASAP PLZ
When an object is placed 55.0cm from a certain converging lens, it forms a real image. When the object is moved to 45.0cm from the lens, the image moves 6.00 cm farther from the lens. Find the focal length of this lens? Please someone help me out I tried so many times i keep g...
