Spectroscopy

Front

What is the light that you can see called?

Back

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from wavelengths of about 400 to 700 nanometers.

Front

What is the emission spectrum of an element?

Back

The emission spectrum is a spectrum of the electromagnetic radiation emitted by a source, which can be used to identify the element based on its unique spectral lines.

Front

Which element is known for having a prominent emission spectrum in the visible range?

Back

Helium is known for its distinct emission spectrum, which can be observed in various astrophysical contexts.

Front

What is the order of visible light colors from longest wavelength to shortest?

Back

The order is Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Front

What type of electromagnetic radiation has the most energy?

Back

Ultraviolet radiation has more energy than infrared, microwaves, and radiowaves.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters or nanometers.

Front

What is the relationship between wavelength and energy in electromagnetic radiation?

Back

The energy of electromagnetic radiation is inversely proportional to its wavelength; shorter wavelengths have higher energy.

Front

What is spectroscopy?

Back

Spectroscopy is the study of the interaction between matter and electromagnetic radiation, used to analyze the composition of substances.

Front

What is the difference between absorption and emission spectra?

Back

Absorption spectra show the wavelengths of light absorbed by a substance, while emission spectra show the wavelengths of light emitted by a substance.

Front

What is a continuous spectrum?

Back

A continuous spectrum is a spectrum that shows all wavelengths of light without any gaps, typically produced by solid, liquid, or densely packed gases.
