What happens to the kinetic energy when temperature is changed?
When the temperature is increased the kinetic energy increases, and when it is decreased the kinetic energy decreases.
What is the nature of energy?
Theories abound but nobody knows.
What happens to the intensity of a bright fringe when the wavelength of the light is increased?
It decreases. This is because the same amount of energy is distributed over a larger area (wavelength increases, so fringe spacing also increases). Energy per unit area decreases and this is why intensity decreases.
What is the nature of dark energy?
Theories abound but nobody knows.
How does light intensity affect the rate of photosynthesis?
Higher light intensity increases the rate of photosynthesis and vice versa.more intense light means more energy in the light, so the chloroplasts get more energy from light, making photosynthesis go faster
What is the wave in which amplitude changes to create sound?
The wave in which amplitude changes to create sound is a sound wave. The intensity of the wave will be changed by energy.
What changes when the intensity the brightness of a light wave changes?
When the intensity of light changes, the number of photons in the beam increases. Keep in mind the beam has larger photon population, but the energy of individual photon is unchanged. The photons only increased in number.
How does the amplitude affect the energy of a wave?
The intensity will increase if the energy increase. The intensity is proportional to the square of the amplitude of a wave.
Does light intensity affect electrical energy?
The more electrical energy there is there is more power or wattage which means that the light intensity is higher if there is more electrical energy.
A measure of a waves energy?
Intensity
What property of a wave is affected by the amount of energy transported?
Intensity of sound is affected. Intensity is the amount of sound energy passing in unit time. Higher intensity sounds can travel longer distances.
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
