Answer:
A.The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves. Amazingly, many musicians, who have been trained are capable of detecting a difference in frequency between two separate sounds that are as little as 2 Hz.
B.Speed of sound in solid is 6000 metres per second while the speed of sound in steel is equal to 5100 metres per second. Another interesting fact about the speed of the sound is that sound travels 35 times faster in diamonds than in the air.
C.IN SPACE, no one can hear you scream. Sound waves are travelling vibrations of particles in media such as air, water or metal. ... So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
