Absorption Spectra

Definition of Absorption Spectrum

• Range of wavelengths of visible light that are emitted by a substance.

• Spectrum of electromagnetic radiation that are transmitted through a substance.

• Range of wavelengths of sound waves that are absorbed by a substance.

• Spectrum of wavelengths of heat radiation that are absorbed by a substance.

Atomic Absorption Spectroscopy

• Identifies the concentration of a specific ion in solution.

• Identifies the spectrums of an ion.

• Used to clean an electron microscope from radiation.

• Identifies the atomic mass of an atom.

Types of Absorption Spectrum

• colour, black, white

• straight, circular, infinite

• line, continuous, band

• spectral, invisible

When does Absorption Spectrum Occur?

• When light hits a solid

• When the lights are turned off

• When light bounces off a metal

• When light passes through a gas

Continuous spectrum

• When a spectrum is infinitely long

• When a spectrum has no space between wavelength range

• When spectral light occurs

• The object used is continuous

Band Absorption Spectrum

• A circular spectrum of lights in a band shape

• Wavelengths that slow down a transition in a substance

• Wavelengths that excite a transition in a substance

• A spectrum that absorbs band shaped light.

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.

What is Absorption Spectroscopy

• Determines how much substance is present in a sample.

• Absorbs spectral scopes.

• The study of spectres in microscopes.

• When light is fully absorbed and turned into spectral light.

What can an Absorption Spectrum tell you?

• That colours exist.

• What elements a star is made of.

• Nothing

• What a spectre absorbs.
