    A student performed the experiment to measure the speed of sound in air using resonance air-column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first resonance and that with the longer air-column 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 $1 \mathrm{~cm}$

    $(D)$ the length of the air-column at the first resonance was somewhat shorter than $1 / 4$ th of the wavelength of the sound in air
