Name the types of progressive wave.

A string 105 cm long is fixed at one end. The other end of string is moved up and down with frequency 15 Hz .A stationary wave, produced in the string , consists of 3 loops. Calculate the speed of progressive waves which have produced the stationary wave in the string.

A string 1 m long is fixed at one end. The other end is moved up and down with frequency 15 Hz . Due to this , a stationary wave with four complete loops , gets produced on the string. Find the speed of the progressive wave which produces the stationary wave [ Hint : Remember that the moving end is an antinode.]

Name the types of poisonous snakes.

Find the distance between two successive nodes in a stationary wave on a string vibrating with frequency 64 Hz . The velocity of progressive wave that resulted in the stationary wave is 48 ms^-1 .

Name the types of telescopes.
