In simple pendulum motion, restoring force is provided by:
The maximum displacement from mean position is called:
the motion in which the friction reduces the mechanical
energy of the system as time passes and the amplitude of motion reduces is
called:
The product of frequency and wavelength is equal to:
Diffraction of wave can be observed clearly only when the
size of slit or obstacle is nearly ………. To the wavelength of the wave:
