Want this question answered?
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.
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.
The longest wavelengths of light are the lowest frequencies (and the lowest energy and the longest period, too). These are the reds, and moving up the spectrum, we encounter orange, yellow, green, blue and violet. The violet light has the shortest wavelength (highest frequency), and the highest energy. The infrared (IR) is below the red (longer wavelength and lower frequency), and the ultraviolet (UV) is above the violet (shorter wavelength and higher frequency).
Physically, light of different colors differs:* In their wavelength * In their frequency (note: the longer the wavelength, the lower is the frequency - so, they are inversely proportional) * In the energy per particle (photon) - proportional to the frequency

550 nm sounds pretty much like a wavelength, so what's the question? It's in the visible spectra, the color green.

Green light. If you use the abbreviation ROY G. Biv ( red, orange yellow, green, blue, indigo, violet), you will always know that the red light has the longest wavelength and violet has the smallest wavelength. Wavelength and frequency are inversely proportional to one another. So if the wavelength is large, frequency is small, and when wavelength is small, frequency is large. Green light has a smaller wavelength than yellow. Likewise it has a higher frequency than yellow does. Therefore, green light has a higher frequency than yellow light.
the photon's energy is either reflected green (because its a leaf) or its absorbed red, because red is the opposite of green and the red is not seen.

The energy is 3,8431.10e-14 joule.
The smaller the wavelength (high frequency), the higher the energy. So gamma has the highest energy, followed by x-rays, UV, visible, infrared, microwaves, radio, in descending order. This is also why green laser-pointers are more expensive than red ones ;)

Hard to believe, but back in the old days, we had red, orange, yellow, green, blue, indigo, and violet. Now, they shorten the list. Who knows what indigo is anyway? Red is the longest wavelength, violet is the shortest. BTW, some people call violet purple, but that's another story.
