Suppose a metal will eject electrons from its surface when struck by yellow light. What will happen if the surface is struck with ultraviolet light? a. No electrons would be ejected.
b. Electrons would be ejected and they would have lower kinetic energy than those ejected by yellow light.
c. Electrons would be ejected and they would have the same kinetic energy by yellow light.
d. Electrons would be ejected and they would have greater kinetic energy than those ejected by yellow light.

d. Electrons would be ejected and they would have greater kinetic energy than those ejected by yellow light.

Explanation:

A formula that describes the kinetic energy of an electron ejected when a surface is truck by light is:

As you see, the higher the energy of the photon striking the surface, the higher the kinetic energy of the ejected electron.

Ultraviolet light has more energy than yellow light, so it would cause the ejected electron to have greater kinetic energy as well.

the answer would be c

the temperature of the gas, in k, not celsius.
