Wave Properties Flashcard

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's propagation.

Front

What is resonance?

Back

Resonance is the natural frequency at which an object vibrates, leading to an increase in amplitude.

Front

What is an antinode in a standing wave?

Back

An antinode is a point of maximum displacement in a standing wave, where the amplitude is greatest.

Front

How many antinodes are present in a standing wave with 6 nodes?

Back

There are 5 antinodes in a standing wave with 6 nodes.

Front

What is the relationship between frequency and period of a wave?

Back

The period of a wave decreases as the frequency increases, and vice versa. They are inversely related.

Front

What is the formula for wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).

Front

What is a harmonic in wave theory?

Back

A harmonic is a frequency that is a whole number multiple of a fundamental frequency.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, particles move perpendicular to the direction of wave propagation, while in a longitudinal wave, they move parallel.

Front

What is the fifth harmonic?

Back

The fifth harmonic is the fifth mode of vibration of a system, typically represented by a specific pattern of nodes and antinodes.

Front

What happens to the wavelength of a wave if the frequency increases while the wave speed remains constant?

Back

The wavelength decreases as the frequency increases, according to the wave speed formula.
