Light intensity is?
Light is composed of quanta called photons. The more photons, the greater the intensity. To see the slightest flicker of green light (the color to which our eyes are most sensitive), the minimum number of photons is six.
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 many photons are there in a beam of light?
More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
What is the relationship between intensity and frequency?
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
Which wave characteristic is affected by the loudness or the intensity of sound?
Amplitude. (In the particle theory of light, brightness is determined by the number of photons).

Define light intensity?
Light is composed of quanta called photons. The more photons, the greater the intensity. To see the slightest flicker of green light (the color to which our eyes are most sensitive), the minimum number of photons is six.
When comparing a beam of red light and a beam of green light which beam contains the greater number of photons?
Neither. The beams of red light and green light will have the same number of Photons, as energy is only related to frequency. The number of Photons is dependent on the intensity of the light beams.

More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
Does kinetic energy of photo electron depend upon intensity of light?
No. Kinetic Energy of a photon depends only on the frequency of the light (or in other words frequency of the photons which the light comprises of). Intensity of light, on the other hand, is a way to talk about how many photons are there in, say, a beam of light (putting it in simple words)!

Is there a light stronger than Gamma?
The highest energy photons are described as Gamma. But in terms of the strength, there are more light sources that we encounter everyday of a greater intensity than gamma, as intensity is a measure of the number of photons arriving over an area in a given time. Therefore, visible light and infra-red from the sun are much more intense than the gamma we encounter everyday, as gamma photons are few and far between.
Which wave characteristic is affected by the loudness or the intensity of sound?
Amplitude. (In the particle theory of light, brightness is determined by the number of photons).
When light is reflected are the lumens reflected too?
Yes. The lumen is a measure of the strength of light; if light may be detected , it is done via the presence of photons, their intensity is the measure of luminosity.
What is the scientific definition for intensity?
Intensity is proportional to the square of the amplitude of vibration in case of mechanical wave such as sound waves But in case of light which is electromagnetic in nature, the intensity is the number of photons crossing unit area in one second
When did Theodore Maiman invent the first light bulb?
In 1960, Theodore Maiman invented the laser while working at Hughes Research Laboratory. The laser emitted photons that struck other photons and generated more photons. The set up allowed for a systematic emission of photons, and after gaining ample intensity they formed a consistent beam of light.
