Question

lesson 27 - properties of waves
which photons have the most energy?
○ photons in yellow light
○ photons in red light
○ photons in violet light
○ photons in blue light

Explanation:

Photon energy follows $E = hf$ (Planck's equation), where $E$ is energy, $h$ is Planck’s constant, and $f$ is frequency. Higher frequency means higher energy. In visible light, violet has the highest frequency, red the lowest.

Answer:

photons in violet light
