This plastic surgeon is using two light sources: a headlamp that emits a beam of visible light and a handheld laser that emits infrared light. The light from both sources is emitted in the form of packets of energy called photons. For which source are the individual photons more energetic? (i) The headlamp; (ii) the laser; (iii) both are equally energetic; (iv) not enough information is given.

Gaseous calcium atoms absorb light at 423, 272, and 240 nm. After a photon of 272 nm is absorbed from the ground state, a photon of wavelength 672 nm is emitted. After absorption of a photon of 240 nm occurs from the ground state, a photon is emitted of wavelength 504 nm. After the 504 nm photoemission occurs, what wavelength of light (in nm) would have to be emitted for an electron to return to the ground state? Construct an energy diagram to help.

Solar panels are a technology that utilize the the photovoltaic effect - a phenomenon very similar to the photoelectric effect! In the photoelectric effect, light is shone on a material's surface. If the wavelength of the light is short enough to supply the amount of energy needed to ionize an atom, then electrons are completely ejected from the material's surface with some nonzero kinetic energy. In the photovoltaic effect, electrons detached from atoms upon the absorption of a photon remain in the bulk material instead of being completely ejected. The electrons freed by the interaction of the sunlight with the semiconductor material creates an electron flow within the absorbing material (typically Silicon) as the free electrons move together around an external circuit. This current, in conjunction with an internal electric field set up by the combination of materials in the solar panel (which can be thought of as a small battery supplying a voltage), allows for the generation of…
A strip of metal foil with a mass of 5.00 × 10-7 kg is suspended in a vacuum and exposed to a pulse of light. The velocity of the foil changes from zero to 1.00 × 10-3 m/s in the same direction as the initial light pulse, and the light pulse is entirely reflected from the surface of the foil. Given that the wavelength of the light is 450 nm, and assuming that this wavelength is the same before and after the collision, how many photons in the pulse collide with the foil?
