Is an oscillation a wave? Explain.

What are resonant oscillations? Explain with the help of suitable examples.

What are transverse and longitudinal waves?Explain with suitable examples.

The coil of a moving-coil galvanometer keeps on oscillating for along time if it is deflected and released. If the ends of the coil are connected together, the oscillation stops at once. Explain.

What do you mean by free and damped oscillations? Explain graphically.

What are coupled oscillations? Explain with the help of suitable examples.

What oscillates in e.m. waves? Give two examples of e.m. waves.

A simple harmonic oscillator at the point x=0 genrates a wave on a rope. The oscillator operates at a frequency of 40.0 Hz and with an amplitude of 3.00 cm. the rope has a linear mass density of 50.0 g//m and is strectches with a tension of 5.00 N. (a) determine the speed of the wave. (b) find the wavelength. (c ) write the wave function y(x,t) for the wave, Assume that the oscillator has its maximum upward displacement at time t=0. (d) find the maximum transverse acceleration at time t=0. (d) find the maximum transverse of points on the rope. (e) in the discussion of transverse waves in this chapter, the force of gravity was ignored. is that a reasonable assumption for this wave? explain.
