Question

(a) Draw the diagram of a right angled isosceles prism which is used to make an inverted Image *****.

(b)

The diagram above shows a wire stretched over a sonometer. Stems of two vibrating tuning forks A and B are touched 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 *** when the stem of vibrating tuning fork B is touched to the wooden box.

(i) Name the phenomenon when the paper rider just vibrates.

(ii) Name the phenomenon when the paper rider flies ***.

(iii) Why does the paper rider fly *** when the stem of tuning fork B is touched to the box?

Answer 1

(a) Diagram is shown in figure for inverted ***** image by Right angle isosceles prism.

(b) (i) When paper just vibrate on the wire of sonometer then phenomenon is called 1st overtone or 2nd harmonics.

(ii) When paper flies ***, then we have fundamental mode or first harmonics.

(iii) Paper files *** by Tuning Fork B, because it produce fundamental mode or first harmonics in wire.
