The perception of how high or low a sound is depends on its frequency. The brain interprets the frequency of sound waves to understand this characteristic.
Sound involves several physical properties like frequency and amplitude, which are perceived by the brain in specific ways:
Therefore, the specific way the brain interprets the frequency of an emitted sound is called its pitch.
The speed of sound __________ as it passes from solid to gaseous medium.
What minimum distance should the reflecting surface be for an echo to be heard?

Frequencies higher than the human audible limit of 20,000 Hz are classified as _____.
What happens to the speed of sound as the temperature of the air increases?
In which of the following media does sound move the fastest at a particular temperature?
What is the approximate speed of sound in air at room temperature (approximately 20\(°C\))?
Which of the following is correct?
I. Sound is a mechanical wave
II. Sound wave does not need any medium to propagate
At a particular temperature, sound propagates in ______ at the fastest speed .
