Explanation:

Lasers are intense beams of light. They are not visible until they reflect or bounce off an object. Rainbows are formed by the refraction, reflection, and dispersion of light in water droplets and are not intense beams. Neon gases emit light when electricity is passed through them but are not in the form of intense beams that are only visible upon reflection like lasers.

Lasers
