How is the frequency of light related to energy?
A photon is a theoretical particle of light.The energy of a photon is directly proportional to the frequency of the light.E = hνwhere E = energy of the photonh = Planck's constant = 6.63 × 10-34 m2 kg s-1ν = frequency of the lightNote: ν in the equation above is not the English letter 'v' but the Greek letter 'nu' (pronounced new).

What change occurs with the atom when it is emitting light?
When an atom emits light, an electron in the atom transitions from a higher energy state to a lower energy state. This transition releases energy in the form of a photon of light. The atom remains the same element before and after emitting light.
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.
Why do atoms of certain elements give off light of characteristic color when heated to high temperature?
Atoms of certain elements give off light of characteristic color when heated to high temperature since the electrons induce to absorb energy, jumps to the excited energy state called quantum jump and then returns to their ground state. The amount of energy in the photon determines its color.
What is the meaning of incandescence?
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
How is the energy of a photon related to its frequency and wavelength?
wavelength : wavelength is the distance from crest of one wave to the crest of next frequency : the number of waves that passes a given point in one second energy : the amplitude or intensity of a wave energy and frequency is directly proportional to each other when energy is high frequency is also high wavelength and frequency or energy is inversly proportional to each other when wavelength is high frequency or energy is low
What do light waves of greater frequency have?
The meaning of a high frequency wave is a shorter wavelength.For electromagnetic waves in general (including light):* At greater frequencies, you get shorter wavelengths.* At greater frequencies, you get more energy per photon.
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 color is visible light sprectrum has the most energy per photon?
A photon's energy is directly proportional to its frequency (inversely proportional to its wavelength).In any given interval of the spectrum, the highest frequency (shortest wavelength) carries the most energy.For visible light, that corresponds to the violet end of the 'rainbow'. The last color your eyes can perceiveat that end is the color with the most energy per photon.
What light packs the highest energy per photon?
The highest energy per photon is found in gamma rays, which are a form of high-energy electromagnetic radiation. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum.
All light has the same amount of energy?
This is a tricky question because there is more than one form of energy in light. There is the energy that each particle of light (the photon) has and there is group energy which is the sum total of all the photon energy as they travel as a group (like in a laser beam). But the good news is that the answer is FALSE for both the photon and group energies. Photon energy depends on the photon fundamental frequency. And the higher the energy the bluer the color, which can run from red to violet. Those photons in the violet color have higher energy than photons in the red color frequency. And group energy is just the sum of all the photon energies in a group, like a light beam from your flashlight (aka, torch). So for a given mix of photons, the more photons in the group the higher is the group energy level. What we call light intensity (e.g., bright or dim) depends on the group energy with high energy equating to high intensity.
What is the energy of a photon?
the energy of a photon is h times f

Does a high frequency wave transmit more energy than a low frequency wave?
No, the energy of a wave is determined by its amplitude, not its frequency. In terms of electromagnetic waves, both high and low frequency waves can carry the same amount of energy per photon. The perceived intensity of a wave is linked to its amplitude, not its frequency.
Does Light photon has more energy than x-ray photon?
Yes, due to the energy of photons/electromagnetic particles being determined by the equations below: E= hv=hc(1/v)= hc/wavelength. Where E= energy, v= frequency in Hz, h= Planck's constant, c= speed of light Electrons have a very short wavelength, and a very high frequency, thus they have much more energy than a beam of light.
Do waves with longer wavelengths have less energy than waves with shorter wavelengths?
A high energy light will have a shorter wavelength than a low energy light. If the wavelength goes down, then the frequency goes up. When calculating energy in the equation, E=hv, frequency (v) is the variable, not the wavelength. So in the equation, if you wanted a more energy (E), you would have the frequency be large. For the frequency to be big, then the wavelength has to be low.
What is the difference between high pitched and low pitched percussion instruments?
High pitch sound has high frequency. Frequency is not energy. The energy in a sound is related to its volume, not its pitch (frequency.) You may be confused by a related fact about light. Light travels in discrete packets of energy called photons. The energy of a single photon is proportional to its frequency, and the brightness of the light is dictated by the number of photons present. (Actually, the number of photons arriving per second.) But the same is not true of sound.
