Question

light energy arrives at earth in tiny packets of energy called
multiple choice
photons
wavelengths
rays
electrons

Explanation:

Light energy is quantized and arrives as discrete packets of energy called photons. Wavelengths are a property of light (distance between wave crests), rays are a model for light propagation, and electrons are subatomic particles (not light energy packets). So the correct option is the one with "photons".

Answer:

A. photons (assuming the first option is labeled A, with the text "photons")
