Write true or false for the following statement: Sound produced by a sounding body of frequency $300 \text{ Hz}$ covers $34 \text{ m}$ in the time the sounding body produces $30$ vibrations.

Define the following characteristics of sound:
$(a)$
$(i)$ Pitch
$(ii)$ Loudness
$(iii)$ Quality or Timbre
$(b)$ $A$ boy receives his echo $3 \, s$ later. Find the distance of the reflecting surface from the boy. Speed of sound in air is $342 \, m s^{-1}$.

If the amplitude of a wave is doubled, what will be the effect on its loudness?

$A$ person fires a gun in front of a building $167 \ m$ away. If the speed of sound is $334 \ m \ s^{-1}$,calculate the time in which he hears an echo. (in $s$)

Draw the sound waves for a low-pitched and a high-pitched sound. Write one use of ultrasonography. Which wave property determines pitch?

If the frequency of a tuning fork is $400 \, Hz$ and the speed of sound in air is $340 \, m/s$. Find how far sound travels when the tuning fork makes $16$ vibrations. (in $m$)
