A vibrator generates the waves of the speed 330ms–1 and wavelength 0.8 m. Then the frequency and time period is
Find the amplitude of vibration of the particles of air through which a sound wave of intensity 2.0 × 10−6W m−2 and frequency 1.0 kHz is passing. Density of air =1.2 kgm−3and speed of sound in air =330ms−1
