Practice CBSE Class 11 Waves & Oscillations in the app →A pendulum bob oscillates as $x(t) = 0.05\cos(2\pi t)$ in metres. Its amplitude and period are:A spring of constant $k = 100$ N/m carries a mass of $1$ kg. Its period of oscillation is:A simple pendulum's length is increased four times. Its period changes by a factor of:A child's swing is pushed gently at its natural frequency and the amplitude grows large. This phenomenon is caA wave on a lake has wavelength $4$ m and frequency $0.5$ Hz. Its speed is:A string of mass per unit length $\mu = 0.01$ kg/m is under tension $T = 100$ N. Wave speed on it is:Two tabla drums sound at $256$ Hz and $260$ Hz simultaneously. The beat frequency heard is:An autorickshaw with horn at frequency $f_0$ moves toward a stationary listener. The listener hears a frequenc
