Answer to Question #298897 in Optics for Chemistry

Question

In what ways do photons resemble other particles such as electrons? In what ways do they differ? Do photons have mass? Do they have electric charge? Can they be accelerated? What mechanical properties do they have?

Answer 1

High frequency photons act like particles when they collide with protons and electrons.

Photons do not have a rest mass, but when they are in motion they have mass.

Photons can't be accelerated because they always travel at the speed of light.

Photons have wavelength and frequency.
