Electromagnetic Spectrum

Front

What is the electromagnetic spectrum (EMS)?

Back

The EMS is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

List the types of waves in the electromagnetic spectrum in order of increasing frequency.

Back

Radio, Micro, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

What is a photon?

Back

A photon is a packet of electromagnetic energy.

Front

In which state does an electron have the least amount of energy?

Back

Ground state.

Front

What is the unique spectral 'fingerprint' of an element?

Back

It is the specific pattern of wavelengths emitted or absorbed by an element, which can be used to identify it.

Front

What is the formula to calculate frequency (v) from wavelength (λ)?

Back

v = c / λ, where c is the speed of light.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.

Front

What happens to the frequency of electromagnetic waves as the wavelength decreases?

Back

The frequency increases.

Front

What is the relationship between energy and frequency of a photon?

Back

Energy is directly proportional to frequency; as frequency increases, energy increases.

Front

What type of electromagnetic radiation has the highest frequency?

Back

Gamma rays.
