"High" and "low" only have meaning when they're compared to something.

compared to X-rays.

Where does the name redshift come from?
The name "redshift" comes from the fact that when the energy of light decreases, the lines of a spectrum, for visible light, will change, or shift, towards the red end - the low energy end. This term is really only appropriate for visible light, but it is generally used for a decrease in energy. In infrared light, a reduction in energy will actually shift the spectrum AWAY from red, but the term "redshift" is still used in this case.The name "redshift" comes from the fact that when the energy of light decreases, the lines of a spectrum, for visible light, will change, or shift, towards the red end - the low energy end.

What form of electromagnetic waves falls just after visible light on the electromagnetic spectrum this form will have higher energy and a shorter wavelenght than visible light?
That depends which way you are moving along the electromagnetic spectrum.If you are moving from low to high frequency, then the last category before visible light is infrared radiation.If you are moving from short to long wavelength, then the last category before visible light is ultraviolet radiation.
Is the frequency of infrared light higher than visible light?
No. X-Rays have a greater frequency than visible light. In order of increasing frequency(or decreasing wavelength). Radio waves, Microwaves, Infra-red radiation, Visible light, Ultraviolet radiation, X-rays, Gamma rays.
Which color has the least amount of energy per photon?
High-energy photons correspond to short-wavelength light while low-energy photons correspond to long-wavelength light. In short, the answer is red. For short-wavelengths (high energy photons) it would appear blue.
What is the amplitude of the visible light spectrum?
It is not meaningful to talk about "amplitude of the visible light spectrum". One might think that more intense light would mean greater amplitude of the light wave, but it just means more photons. "Visible light" is made up of photons. A single photon has a certain quantifiable energy, and that energy is discussed in terms of frequency or wavelength. A photon with low frequency (towards the red end of the visible light spectrum, for instance) is less energetic than a photon with high frequency (towards the blue end and beyond). For all intents and purposes, the amplitude of a photon wave-packet could be said to be of "unit amplitude", the amplitude of light.
Does infrared high or low energy?
Infrared radiation has less energy (per photon) than visible light.
Red light is low energy and has long wavelengths?
Violet light has a short wavelength, high frequency, and high energy. Red light has a much higher wavelength than violet light.
What is the job of a light bulb?
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)

Electromagnetic radiation in order of decreasing energy per photon?
The types of electromagnetic radiation in order of decreasing energy per photon is gamma rays, visible light, microwaves, and radio waves. All of the rays include cosmic rays, gamma rays, x-rays, ultra violet light, visible light, infrared light, microwaves, and radio waves.
What are low energy waves found in electromagnetic spectrum called?
as in microwave radio and tv maybe include infared and visible light they all have a reasonably low frequency and energy. (the lower the frequency the less energy)
Why is the light given off as fluorescence always of lower wavelength than the light absorbed?
It isn't. The usual way fluorescence works is indeed that a high energy light promotes an electron to a high energy state and it then cascades down through the energy levels giving off low energy quanta of light at each step. However there is the situation where low energy light input can act as an energy pump and promote an electron in a series of energy steps to a high energy state which it then releases in a single high energy drop emitting a quantum of light of a higher energy than the input.
Do ultraviolet waves have a high or low frequency?
That depends what you call "high" or "low". The frequency of ultraviolet waves is higher than that of visible light; lower than that of x-rays.
Is the frequency of infrared light higher than visible light?
No. X-Rays have a greater frequency than visible light. In order of increasing frequency(or decreasing wavelength). Radio waves, Microwaves, Infra-red radiation, Visible light, Ultraviolet radiation, X-rays, Gamma rays.
What are some example of light energy?
Light energy is the energy carried by photons. Although there aren't really different types of light, we separate these out by frequency and wavelength so we can better identify what they can and will do. They range from very low to extremely high frequency; radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
Which color has the least amount of energy per photon?
High-energy photons correspond to short-wavelength light while low-energy photons correspond to long-wavelength light. In short, the answer is red. For short-wavelengths (high energy photons) it would appear blue.
