Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its amplitude, wavelength, frequency, and speed.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).

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 is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, which depends on the wavelength and the size of the obstacle.

Front

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 wave source.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are 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 electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

What is sound?

Back

Sound is a type of mechanical wave that travels through a medium (solid, liquid, or gas) as a result of vibrations.
