UV has higher energy (per photon) than visible light.


What might the photon from 9.7210-8 be useful for?

would be useful for getting a suntan, since this wavelength falls in the category of UV rays.


What is the frequency of a UV photon at 350nm?

The frequency of a UV photon with a wavelength of 350 nm can be calculated using the equation: frequency = speed of light / wavelength. The speed of light is approximately 3.00 x 10^8 m/s. Plugging in the values, we find that the frequency of a UV photon with a wavelength of 350 nm is approximately 8.57 x 10^14 Hz.

Gamma rays. Each individual photon is more energetic, at any rate.


Why are ultraviolet rays more harmful to the skin than visible light?

That's related to the fact that UV rays have more energy per photon.


Will indium display the photoelectric effect with UV light?

Yes, indium can display the photoelectric effect when exposed to UV light. When UV light shines on a metal surface like indium, electrons are ejected from the surface due to the photon energy exceeding the work function of the metal. This phenomenon is known as the photoelectric effect.


Does UV radiation have more energy than violet light?

Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter


When a photon is absorbed by a molecule what happens to the photon?

When a photon is absorbed by a molecule, it transfers its energy to the molecule's electrons, causing them to become excited or move to a higher energy state. This can lead to various chemical reactions or physical changes in the molecule.

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.


What is the opposite of a photon?

The opposite of a photon is an antiphoton.
