Another name for light is

Karo-lina-s [1.5K]

Answer:

Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨

Explanation:

Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves (used in microwaves), Infrared Radiation (heat), Visible Light (the colors we see), Ultraviolet (the UV radiation that causes sunburns), X-Rays (used in medical X-Rays), and Gamma Rays (which can be used to treat cancer). Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.

I hope this helps!
