Harmonics

Front

What is harmonics?

Back

Harmonics refers to the study of the frequencies of waves that are integer multiples of a fundamental frequency, often observed in musical instruments and sound waves.

Front

What is the fundamental frequency of a vibrating string?

Back

The fundamental frequency is the lowest frequency at which a string vibrates, producing its first harmonic.

Front

How many wavelengths fit in a string vibrating at its fundamental frequency?

Back

1/2 wavelength.

Front

What happens to the amplitude of a sound wave when the sound becomes louder?

Back

The amplitude increases.

Front

What is the relationship between frequency, wavelength, and speed of sound?

Back

The speed of sound (v) is equal to the frequency (f) multiplied by the wavelength (λ): v = f × λ.

Front

What is the equation for the frequency of a vibrating string?

Back

f = n(v/2L), where n is the harmonic number, v is the wave speed, and L is the length of the string.

Front

What is the first harmonic of an open tube?

Back

The first harmonic (fundamental frequency) of an open tube has a wavelength that is twice the length of the tube.

Front

What is the fourth harmonic of an open tube?

Back

The fourth harmonic has a wavelength that is half the length of the tube, producing three antinodes.

Front

What type of wave is produced on a string?

Back

Transverse wave.

Front

What type of wave is produced in an open tube?

Back

Longitudinal wave.
