Question

explain why light is referred to as electromagnetic radiation. it is a traveling wave of oscillating electric and magnetic fields. it requires a medium to travel, like all waves. we know light is radiation due to the harmful effects it produces when exposed to it for long periods of time. it is a spectrum which only includes what we can see with our eyes.

Explanation:

Light is an electromagnetic wave consisting of oscillating electric and magnetic fields. It does not require a medium to travel (unlike mechanical waves) and the electromagnetic spectrum includes more than just visible light. Also, not all light - related radiation has harmful effects.
