Front

White light passing through a prism:

Back

Bends and disperses into a rainbow.

Front

Colors on a light spectrum are labeled in plural (e.g., 'Reds') to reflect the variety of shades within each color.

Back

Variety of shades within each color.

Front

Do all colors of light travel at the same speed in a vacuum?

Back

Yes, all light travels at the same speed in a vacuum.

Front

Colors of light: highest energy - violet, lowest energy - red.

Back

Violet: highest energy, Red: lowest energy.

Front

Visible spectrum colors: longest and shortest wavelengths?

Back

Red: longest, violet: shortest.

Front

Relationship between wavelength and energy of light.

Back

Shorter wavelength = higher energy.

Front

Hydrogen gas discharge tube creates a spectrum of light by exciting electrons that emit specific wavelengths when returning to lower energy levels.

Back

Excited electrons emit specific wavelengths.

Front

Color of light from an atom indicates its electronic structure by revealing energy levels of its electrons.

Back

Reveals energy levels of electrons.
