UV photons vs. photons of visible light

Postby Alexandra Bartolome 2H » Sat Oct 12, 2019 4:41 pm

What causes ultraviolet photons to be more energetic than photons of visible light? Is it simply due to the fact that ultraviolet light has higher frequencies and shorter wavelengths than visible light?

Yes, by definition, UV light has higher energy/frequency and shorter wavelengths than visible light, which is light with a wavelength range that is visible to the human eye.

Yes, the energy of a photon of light is equal to Planck's constant times frequency, so as frequency increases (as when going from visible light to UV) energy also increases.
