When does Absorption Spectrum Occur?

• When light hits a solid

• When light bounces off a metal

• When light passes through a gas

Line Absorption Spectrum

• The dark lines/gaps that correspond to wavelengths.

• A spectrum that is a straight line.

• A substance that only absorbs straight wavelengths.

• The coloured spaces that correspond to wavelengths.
