Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, arranged in order of increasing frequency and decreasing wavelength.

Front

What is the frequency of infrared waves?

Back

The frequency of infrared waves is approximately 10^12 Hz.

Front

What type of telescope is used to observe X-ray wavelengths?

Back

An X-ray telescope is used to observe celestial objects emitting X-ray wavelengths.

Front

Which section of the electromagnetic spectrum can humans see?

Back

Humans can see the visible light section of the electromagnetic spectrum.

Front

Arrange the following forms of electromagnetic energy from longest to shortest wavelength: Microwave, Infrared, Visible Light.

Back

Microwave -> Infrared -> Visible Light.

Front

What is the wavelength of visible light?

Back

The wavelength of visible light ranges from approximately 400 nm (violet) to 700 nm (red).

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What type of electromagnetic radiation has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

Front

What is the primary use of radio waves?

Back

Radio waves are primarily used for communication, including radio and television broadcasting.

Front

What is the definition of ultraviolet rays?

Back

Ultraviolet rays are a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.
