Question

In which case is the speed of sound more: the humming of a Bee or the roaring of a Lion?

Answer 1

Hint: The speed of sound shows us the rate at which sound moves from the sound-producing body to our ears. In the given question, both the humming of a Bee or the roaring of a Lion varies in amplitude. So, it does not affect the speed of the sound but affects the loudness of the sound.

Complete answer:
The factors on which the sound's speed depends:
1) Medium's density: The sound's speed is inversely proportional to the medium's density.
2) Medium's Humidity: More wet the air is, the higher the speed of sound.
3) Medium's temperature:The speed of sound is directly proportional to the absolute medium's temperature.
The loudness of the sound is directly proportional to the wave's amplitude. The amplitude of the wave defines the sound wave's loudness. A higher amplitude means a loud sound, while a shorter amplitude means a melodious sound. If the amplitude is large, then the sound will be more powerful, and the sound will be weak if the amplitude is less. Loudness is proportional to the amplitude's square. The loudness of the sound rises with an increment in the amplitude vibration.
The speed of sound is independent of the sound's amplitude. So, both the sounds i.e., The humming of a Bee and the roaring of a Lion move at equal speed but vary in loudness due to variation in amplitudes.


Note: The ​pitch​ of a sound is a description of the sound frequency. Several pitches correspond to various frequencies. A high pitch indicates high frequency, and a low pitch indicates low frequency. Pitch can also be defined as the sound quality that enables labeling it as “higher” or “lower” to our ear.
