Questions: Electromagnetic waves are also known as The electromagnetic spectrum is made up of regions. These regions are: Radio waves have wavelength ( λ ) and frequency. Gamma waves have wavelength (λ) and frequency. Visible light makes up a portion of the electromagnetic spectrum. What does a prism do? has the longest wavelength in the visible range. has the shortest wavelength in the visible range. When all wavelengths of the visible spectrum hit your eye at the same time, you see When atoms absorb energy, electrons move away from the nucleus and are called excited electrons. Electrons instantly move back to their original spots. When they do, light is Because every element has a unique arrangement of , each element gives off a different wavelength of light.

Electromagnetic waves are also known as \(\boxed{\text{light waves}}\).

The electromagnetic spectrum is made up of \(\boxed{\text{different regions based on wavelength and frequency}}\).

These regions are: \(\boxed{\text{radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays}}\).

Radio waves have \(\boxed{\text{long wavelengths}}\) and \(\boxed{\text{low frequencies}}\).

Gamma waves have \(\boxed{\text{short wavelengths}}\) and \(\boxed{\text{high frequencies}}\).

Visible light makes up a \(\boxed{\text{small portion}}\) of the electromagnetic spectrum.

A prism \(\boxed{\text{disperses light into its constituent colors}}\).

\(\boxed{\text{Red}}\) has the longest wavelength in the visible range.

\(\boxed{\text{Violet}}\) has the shortest wavelength in the visible range.

When all wavelengths of the visible spectrum hit your eye at the same time, you see \(\boxed{\text{white light}}\).

When atoms absorb energy, electrons move \(\boxed{\text{to higher energy levels}}\) away from the nucleus and are called excited electrons.

Electrons instantly move back to their original spots. When they do, light is \(\boxed{\text{emitted}}\).

Because every element has a unique arrangement of \(\boxed{\text{electrons}}\), each element gives off a different wavelength of light.
