Analysis of Atomic Spectra Lab

Front

What is the formula to calculate the frequency of light?

Back

Frequency (ν) = Speed of Light (c) / Wavelength (λ) where c = 3.00 x 10^8 m/s.

Front

What is the wavelength of light emitted by an argon ion laser?

Back

488 nm (nanometers) or 4.88 x 10^-7 m.

Front

What is the frequency of light with a wavelength of 488 nm?

Back

6.15 x 10^14 Hz.

Front

What type of spectrum is produced by an element when it emits light?

Back

Emission spectrum, which shows bright lines.

Front

What is a spectroscope?

Back

A device that separates light into its different wavelengths or colors.

Front

What type of spectrum shows all wavelengths without gaps?

Back

Continuous spectrum.

Front

What is the purpose of a spectroscope?

Back

To analyze the wavelengths of light emitted or absorbed by substances.

Front

What is an absorption spectrum?

Back

A spectrum that shows dark lines where light has been absorbed by a substance.

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as wavelength increases, frequency decreases.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.
