Stata the effect on the loudness and pitch of the sound from the loudspeaker when the amplitude increases but the frequency of sound stays the same. Pls answer in 2 mins. i will mark brainliest.
Answers
(a) Regions of higher pressure : Compressions Regions of lower pressure : Rarefactions. (b) Production of regions of higher pressure : when the loudspeaker cone moves forward, i.e., in the direction of propagation of wake, it pushes the layer of air closer. This air layer pushes the next air layer, and process goes on. In this way, the layers of air near the cone are compressed to form a compression, which is a region of higher pressure. Production of regions of lower pressure: when the cone moves backward, i.e., away from direction of propagation of wave, it leaves a region of low pressure and the air layers move apart to form a rarefaction. (c) (i) Loudness increases as greater the amplitude of sound waves, louder the sound will be pitch remains same. (ii) Loudness remains same. Pitch increases as the pitch of a sound is directly proportional to its frequency.
Answer: ... Pitch increases as the pitch of a sound is directly proportional to its frequency
