Physics Waves Flashcard

Front

Define 'waves' in the context of physics.

Back

A form of energy transfer.

Front

What does 'frequency' measure in a wave?

Back

Cycles per second.

Front

How is 'speed' related to waves?

Back

Speed = Frequency x Wavelength; m/s.

Front

Define 'medium' in the context of wave propagation.

Back

Substance through which a wave travels.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength is inversely proportional to frequency; as frequency increases, wavelength decreases.

Front

What is the formula for calculating wave speed?

Back

Wave speed = Wavelength x Frequency.

Front

What are the units of frequency?

Back

Hertz (Hz), which is equivalent to cycles per second.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What is amplitude in the context of waves?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resultant displacement is the sum of the individual displacements.
