What is the effect of frequency of incident light on photoelectric current?
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.
What is the relationship between kinetic energy electric energy and generator?
It ends up with energy
What are the four interactions light can have with matter?
photoelectric effect increase in kinetic energy. heat and temp expansion reflection
Does wavelength of the incident rays play a role in the phenomenon of photoelectric effect?
Yes definitely. Reciprocal of wavelength is proportional to frequency as lambda = v /frequency. v - the speed of the wave. The frequency has to be greater than some minimum value known to be the threshold frequency. As frequency increases then kinetic energy of the photo electron also increases. If the frequency of the incident photon is less than the threshold and however higher the intensity, there is no chance of ejection of photo electron right from the surface of the substance. So no photo electric emission is possible.
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
What is the relationship between a kinetic an potential energy?
When potiental increases, kinetic decreases and vice versa.

What is the relationship between stream erosion and kinetic energy?
It is direct, and the amount of stream erosion increases, kinetic energy increases also.
What is the relationship between kinetic energy of molecules and their physical state?
The relationship between kinetic energy of molecules and their physical state is simple. The higher the kinetic energy the faster the molecules move. The fastest moving molecules are gaseous and the slowest moving molecules are solids.
