The violet light has more energy than the red light. Red light is lower on the electromagnetic spectrum, meaning it has a lower frequency (or longer wavelength). You'll recall the colors of the rainbow as red, orange, yellow, etc., and these are the colors going up the frequency spectrum. Photons higher on the spectrum are higher in frequency and energy.
What else can I help you with?
Why does violet has the most energy?
Violet light has the most energy among visible light because it has the shortest wavelength and highest frequency. The energy of a photon is directly proportional to its frequency, so higher frequency light like violet light carries more energy.
Why does violet light has more energy than a red light?
Violet light has a shorter wavelength and higher frequency than red light. Energy of a photon is directly proportional to its frequency, so violet light has more energy than red light.
Does UV radiation have more energy than violet light?
Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter
Why is the photoelectric effect more effective with violet light than with red light?
Violet light has a higher frequency and shorter wavelength compared to red light, which means each violet photon carries more energy. This higher energy of violet light photons allows them to more easily overcome the work function of the material and eject electrons, making the photoelectric effect more effective with violet light than with red light.
Which is more energetic a red photon or a blue photon?
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.

Why won't a very bright beam of red light impart more energy to an ejected electron than a feeble beam of violet light?
The energy of a photon is determined by its frequency, not its intensity. Violet light has a higher frequency than red light, which means each violet photon carries more energy. Thus, even though the red beam may be more intense, the individual photons in the violet beam can still impart more energy to the ejected electron.

This higher energy of violet light photons allows them to more easily overcome the work function of the material and eject electrons, making the photoelectric effect more effective with violet light than with red light.
Is ultraviolet radiation a higher or lower energy radiation than visible light?
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
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.
Which is more energetic a red photon or a blue photon?
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
Which colour light has the most energy per photon?
Violet is the visible light color that has the highest energy photons. Ultraviolet and X-rays aren't really "colors", but they have even more energy per photon.Basically, the energy is proportional to the frequency, so the higher the frequency, the higher the energy.
Does the brightest color in the visible spectrum have the highest energy level?
Yes, the brightest color in the visible spectrum (violet) does have the highest energy level due to its shorter wavelength. Violet light has the highest frequency and carries more energy per photon compared to other colors in the visible spectrum.
Does visible light have more or less energy than ultraviolet light?
Well, first of all, protons don't make light. I think you mean 'photons'. A photon of ultraviolet light carries more energy than a photon of visible light, because it has a higher frequency / shorter wavelength.
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.
