What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, X-rays, and more, categorized by wavelength or frequency.

What is a unique spectral 'fingerprint'?

Back

A unique spectral 'fingerprint' refers to the specific pattern of wavelengths absorbed or emitted by an element, which can be used to identify the element.

Front

What is absorption spectra?

Back

Absorption spectra are produced when a gas absorbs specific wavelengths of light, resulting in dark lines on a continuous spectrum.

Front

What is emission spectra?

Back

Emission spectra are produced when atoms or molecules emit light at specific wavelengths, resulting in bright lines on a dark background.

Front

What is spectroscopy?

Back

Spectroscopy is the study of how matter interacts with electromagnetic radiation, including how it absorbs and emits light.

Front

What happens when an electron absorbs energy?

Back

When an electron absorbs energy, it moves to a higher energy level or excited state.

Front

What happens when an electron emits energy?

Back

When an electron emits energy, it falls back to a lower energy level, often releasing light in the process.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

Which type of electromagnetic radiation has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

Which type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.
