Review on Waves

Front

What does the loudness of sound depend on?

Back

Amplitude

What does the pitch of sound depend on?

Back

Frequency

Front

A string of length L oscillates at a frequency at which a standing wave is produced. What is the wavelength of the wave in the string?

Back

2L/5

Front

If light strikes a plane mirror at a 45° angle, what angle will it reflect?

Back

45°

Front

What is the wavelength of a wave if a snapshot of the wave shows it to be 1.5 m?

Back

1.5 m

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is the relationship between frequency and wavelength in waves?

Back

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

Front

What is the formula for the speed of a wave?

Back

Speed = Frequency × Wavelength

Front

What is a standing wave?

Back

A standing wave is a wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.

Front

Explain the principle of reflection of light.

Back

The angle of incidence is equal to the angle of reflection.
