Here I am giving you question paper for IIT JEE physics subject entrance examination in PDF file attached with it so you can get it easily.

A student performed the experiment to measure the speed of sound in air using resonance
aircolumn
method. Two resonances in the aircolumn
ware obtained by lowering the
water level. The resonance with the shorter aircolumn
is the first resonance and that with
the longer aircolumn
is the second resonance. Then,
(A) the intensity of the sound heard at the first resonance was more than that at the second
resonance
(B) the prongs of the tuning fork were kept in a horizontal plane above the resonance
tube
(C) the amplitude of vibration of the ends of the prongs is typically around 1 cm
(D) the length of the aircolumn
at the first resonance was somewhat shorter than 1 / 4 the
of the wavelength of the sound in air
