Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

What is wavelength?

Back

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

Front

What happens to energy as the frequency of an electromagnetic wave increases?

Back

As the frequency of an electromagnetic wave increases, the amount of energy in that wave also increases.

Front

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

Back

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

Front

What is the speed of light (c) in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.

Front

How do you calculate wavelength (λ) using frequency (f)?

Back

Wavelength (λ) can be calculated using the formula λ = c/f, where c is the speed of light.

Front

What type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength and the highest frequency/energy.

Front

List the types of electromagnetic waves in order from low energy to high energy.

Back

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

Front

What is the frequency of blue light with a wavelength of 4.34 x 10^-7 meters?

Back

The frequency can be calculated using f = c/λ, which gives approximately 6.91 x 10^14 Hz.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position to the crest or trough.
