String of length L = 1.2 m is attached at one end to a wave oscillator, which is vibrating at a frequency f = 80 Hz. The other end of the string is attached to a mass hanging over a pulley as shown in the diagram below.
When a particular hanging mass is suspended from the string, a standing wave with two segments is formed. When the weight is reduced by 2.2 kg, a standing wave with five segments is formed. What is the linear density of the string?
A standing wave is formed in the string pictured in the problem. If a standing wave with two segments is formed when the frequency is 60 Hz and the hanging mass and string length are kept constant, what frequency would be required to produce a standing wave with segments?
