Why is a progressive wave described mathematically?

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 .

Why is genetic code described as degenerate?

Define:Escape velocity and derive mathematically .

Name the types of progressive wave.

How is Lenz's Law represented mathematically?

Write the mathematical equation representing a progressive wave travelling in the negative x-direction with constant speed v.

Progressive wave with doubly periodic means

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.]
