Waves

Front

What shows wavelengths and frequencies?

Back

Electromagnetic Spectrum

Front

Define wavelength.

Back

The distance between successive crests of a wave, typically measured in meters.

Front

What is frequency?

Back

The number of waves that pass a given point per second, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time, calculated as speed = wavelength × frequency.

Front

What are electromagnetic waves?

Back

Waves that can travel through a vacuum and do not require a medium, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the visible spectrum?

Back

The portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).

Front

What is amplitude in a wave?

Back

The maximum displacement of points on a wave from its rest position, related to the energy of the wave.

Front

What is a transverse wave?

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave's travel, such as light waves.

Front

What is a longitudinal wave?

Back

A wave in which the motion of the medium is parallel to the direction of the wave's travel, such as sound waves.
