When a stone is dropped into the river,certain waves are formed on its surface. What type of wave it is?

When a stone is dropped into the river,certain waves are formed on its surface. derive a mathematical expression for the above wave.

When a pebble is dropped,to the surface of water,certain waves are formed on the water surface. Is it a progressive wave?Explain.

When a pebble is dropped,to the surface of water,certain waves are formed on the water surface. The equation for such a wave is y=4sinπ(2t-0.01x) ,Where y and x are in cm and t in seconds,Find its a)amplitude, b)wave length, c)initial phase, d)Frequency.

When copper is placed in the atmosphere for sufficient time, a green crust is formed on its surface. The composition of the green crust is:

A stone is dropped into a quiet lake and waves move in circle at the speed of 5 cm/s. At the instant when the radius of the circular wave is 8 cm, how fast is the enclosed area increasing.
