A signal generator, amplifier and loudspeaker are used to produce different sound waves in theair of a room. The relationships between the properties of these waves are investigated.Which relationship is not correct?A Amplitude is proportional to wavelength.B Frequency is inversely proportional to wavelength.C Intensity is proportional to amplitude squared at a given frequency.D Period is equal to the reciprocal of frequency.

: Which of the following is proportional to the amplitude of the sound where the frequency remainsconstant?

Loudness of a sound wave varies directly with the vibrating body’s(a) Intensity(b) Frequency(c) Amplitude(d) Quality

The amplitude of a sound wave

State what happens to the amplitude and the wavelength of the wave if1. the loudness of the sound is increased at constant pitch,amplitude ...................................................................................................................wavelength ................................................................................................................

Which pairing of terms is incorrectly related? frequency of sound waves: loudness of the sound amplitude of a sound: intensity of the sound frequency of sound waves: number of wavelengths quality of a sound: frequency of the sound
