Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by oscillations.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is frequency in the context of waves?

Back

Frequency is the number of oscillations or cycles that occur in a unit of time, typically measured in hertz (Hz).

Front

How is wavelength defined?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is amplitude in a wave?

Back

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

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the oscillations occur in the same direction as the wave travels, such as in sound waves.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the oscillations occur perpendicular to the direction of wave travel, such as in light waves.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.
