Does intensity increase as frequency increases?
There are many ways of defining the intensity of light, but if you are just measuring the energy per unit time per unit area then yes increasing the frequency while keeping the number of photons constant will increase the intensity.
What will happen to the intensity of light if frequency increases?
if N is the monochromatic photon emission rate (photons per second), ν is the frequency of the photons, and A is the area these photons are hitting. If the only thing one changes is the frequency of the photons, then doubling the frequency will double the intensity.
if you consider light is wave, intensity is related to light radiation energy and frequency is the number of waves per second. Frequency is related to photon’s energy (E = hν , E is energy, h is planck’s constant and ν is frequency) . In particle nature, intensity is related to number of photons in the radiation.
Does frequency determine intensity of light?
That is correct. The intensity of a beam of light is related to the number of photons. Higher frequency – greater energy. More photons – greater intensity.
Does intensity of light change frequency?
A photon is the smallest possible quantum of light. In general when you turn up the intensity of light you are increasing the number of photons per second that are emitted by the light source. Therefore the intensity of the light can indeed be changed independently of the frequency (or color) of the light.
Is intensity inversely proportional to frequency?
There is no such relation in general. Intensity is power/area. power is proportional to frequency so intensity is proportional to frequency.
What affects intensity of light?
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength. Both Wave 1 and Wave 2 have the same wavelength but different amplitudes. The wavelength of light is an important property for it is this that determines the nature of the light.
What does intensity of light depend on?
amplitude of
The intensity of a wave is directly proportional to the amplitude of the wave. Light is an electromagnetic wave. its intensity will depend on the amplitude of the wave.
Can we change frequency of light?
Frequency of light does not ever change, as long as you can be sure that the photons are the same as the photons at the beginning. Wavelength L is, on the other hand, tied with energy through its speed, E=hf=hv/L .
Why does frequency change during refraction?
Wave speed, frequency and wavelength in refraction Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
