Figure $X$ showa a trace of a sound wave produced by a particular tuning fork:
On the graph paper given in Figure $Y,$ draw a trace of the sound wave which has higher frequency than that shown in Figure $X.$
On the graph paper shoen in Figure $Z,$ draw a trace of the sound wave which has a larger amplitude than that shown in Figure $X.$

A sound producing body is at considerable distance from a man. There can be four different media $W, X, Y$ and $Z$ between the sound producing body and the man. The medium $X$ brings the sound to man most quickly whereas medium $Z$ takes the maximum time. The time taken by medium $W$ in bringing sound to man is less than that of $X$ but more than that of $Z.$ The medium $Y,$ however, fails to bring the sound from the sound producing body to the man. Which medium could be the one:
Having no fixed shape and no fixed volume$?$
Having a fixed volume but no fixed shape$?$
Having the same composition as that on the moon$?$
Three different vibrating objects produce three types of sounds $X$, $Y$ and $Z$. Sounds $X$ and $Y$ cannot be heard by a man having normal range of hearing but sound $Z$ can be heard easily. The sound $X$ is used in hospitals to break kidney stones of a patient into fine grains whioch then get flushed out with urine. The sound $Y$ is similar to that which is produced during an earthquake before the main shock wave is generated.
What t$Y$pe of sounds are $(i) X, (ii) Y$, and $(iii) Z$?
Name one device which can produce sound like $X$.
Name one device in a science laboratory which can produce sound like $Y$.
Name one device in our homes which can produce sound like $Z$.
In an experiment, Anhad studies sound waves. He sets up a loudspeaker to produce sound as shown below:
Anhad adjusts the signal to the loudspeaker to give a sound of frequency 200Hz.
What happens to the air in-between Anhas and the loudspeaker?
