1) Light of wavelength 310nm is shined on a metal with work function = 1 eV. What will be the maximum kinetic energy of the emitted electrons? 2) Light is shined on a metal with work function 2.0 eV, and electrons are emitted creating a photocurrent. When a decelerating voltage of magnitude 1.0 V is applied, the current goes to zero (i.e. the magnitude of the stopping voltage is 1V). What is the wavelength (in nm) of the incoming light?...
Energy comes in many different forms, but they share a common bond - they are the source of change, the root of the force. Energy moves through our world by force and action, changing from one form to another. Of course the energy is really the same, but it is our human need to classify what we see that creates the separate designations. We artificially separate energy into different categories for our ease of use. For most of these categories...
