8. Consider two pulses propagating in opposite directions along a string. The picture shows the profile of the string at t = 0 and at t = 2 seconds. Draw the profile of the string at t = 6 and t = 8 seconds. t-0 t=2s t=6s t=8s This is the same situation as above, except that the pulse traveling to the left has been inverted. The picture shows the situation at t = 0 s. Draw the profile of the string at t = 5, t = 6 and t = 8 t seconds. t=5s t=6s t=10 s

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
