Show that all harmonics are present on a stretched string between two rigid supports.

Two strings of same material are joined to form a large string and is stretched between rigid supports. The diameter of the second string is twice that of the first. It was observed in an experiment that the whole string was oscillating in 4 loops with a node at the joint. Find the possible lengths of the second string if the length of first string is 90 cm.

The length of a string tied between two rigid supports is 50 cm. The maximum wavelength of a stationary wave produced on it is
