What is light energy?

Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

Does light lose energy?

A photon doesn’t lose energy unless it collides with a particle. Photons can scatter off interstellar electrons, for example. (Perhaps you were thinking about particles, like electrons, losing energy “in transit” in a vacuum. Photons carry energy, but they don’t lose energy just because they travel.
