What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the wave.

Front

What happens to the wavelength of sound as the source moves towards an observer?

Back

The wavelength decreases as the source moves towards the observer.

Front

What happens to the frequency of sound as the source moves towards an observer?

Back

The frequency increases as the source moves towards the observer.

Front

Define red shift in the context of light waves.

Back

Red shift occurs when light from an object is stretched to longer wavelengths, indicating that the object is moving away from the observer.

Front

Define blue shift in the context of light waves.

Back

Blue shift occurs when light from an object is compressed to shorter wavelengths, indicating that the object is moving towards the observer.

What is electromagnetic radiation?

Back

Electromagnetic radiation is a form of energy that travels through space at the speed of light and includes a range of wavelengths, from radio waves to gamma rays.

Front

List the types of electromagnetic radiation from longest wavelength to shortest wavelength.

Back

Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-rays, Gamma rays.

What is a spectrascope used for?

Back

A spectrascope is an instrument used to observe the spectrum of light emitted or absorbed by substances.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is the significance of the electromagnetic spectrum in spectroscopy?

Back

The electromagnetic spectrum provides a range of wavelengths that can be analyzed to determine the composition and properties of materials.
