The stem of a tuning fork is pressed against a table top. Answer the following questions:
$(i)$ Would the above action produce any audible sound?
$(ii)$ Does the above action cause the table to set into vibrations?
$(iii)$ If the answer above is yes,what type of vibrations are they?
$(iv)$ Under what conditions does the above action lead to resonance?

(N/A) $(i)$ Yes,the above action produces an audible sound because the surface area of the table is much larger than the tuning fork,which helps in vibrating a larger volume of air.
$(ii)$ Yes,the above action causes the table top to set into vibrations.
$(iii)$ These vibrations are known as forced vibrations.
$(iv)$ Resonance occurs when the frequency of the tuning fork is equal to the natural frequency of oscillation of the table top.
