Physics

In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the metal are held constant. Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, what happens if the intensity of the incident light is increased?

In another experiment, the intensity of the incident light and the temperature of the metal are held constant. Assuming that the initial light incident on the metal surface causes electrons to be ejected from the metal, what happens if the frequency of the incident light is increased?

How does the de Broglie wavelength of an electron change if its momentum increases?

How does the de Broglie wavelength of an electron change if its kinetic energy decreases?

Metal surfaces on spacecraft in bright sunlight develop a net electric charge. Do they develop a negative or a positive charge?

Do the molecules in a red cone (which are tuned to absorb red light) or the molecules in a blue cone (tuned to absorb blue light) have a longer "box"?

In a photoelectric effect experiment, the intensity of the light is increased while the frequency is held constant.As a result,

In a photoelectric effect experiment, the frequency of the light is increased while the intensity is held constant.As a result,

In the photoelectric effect, electrons are never emitted from a metal if the frequency of the incoming light is below a certain threshold value.
