What is a Black Body Example?

Answer: A black body is a physics idealisation of a body that absorbs all incident electromagnetic radiation, regardless of frequency or angle.

An ideal black substance in thermal equilibrium has the following two characteristics:

• Ideal emitter: The body emits more thermal radiation energy than any other body at any frequency and at any temperature.
• Spreading emitter A unit area perpendicular to the direction is used to measure this.

• When light enters the cavity through the hole of the black body when it strikes the cavity, no light is reflected from the cavity.
