Using suitable diagram explain how sound wave propagates through air from a vibrating tuning fork?

Explain how sound is propagated as a longitudinal wave .

Draw diagrams to show the loop formation in a vibrating tuning fork.

When a sound wave travels from water to air , it

(a) Draw diagrams to show the longitudinal mode of vibration and transverse mode of vibration of an electrically maintained tuning fork in the Melde's experiment. (b) Indicate with the help of a diagram the positions of nodes and antinodes on a vibrating tuning fork.

Explain why transver waves cannot be propagated through fluids?

The diagram below shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and B are touched in turn to the wooden box of the sonometer. It is observed that the paper rider (a small piece of paper folded at the centre) present on the wire flies off when the stem of vibrating tuning fork B is touched to the wooden box but the paper just vibrates when the stem of vibrating tuning fork A is touched to the wooden box. Name the phenomenon when the paper rider just vibrates.

When a tuning fork (vibrating) is held close to ear, one hears a faint hum. The same (vibrating tuning fork) is held such that its stem is in contact with the table surface, then one hears a loud sound. Explain.

A light pointer fixed to one prong of a tuning fork touches gnetly a smoked vertical plate. The fork is set vibrating and the plate is allowed to fall freely. 8 complete oscilllations are counted when the plate falls through 10cm.What is the frequency of the tuning fork?
