Solve the following question given below:
Question: In an experiment on standing waves, a string 90 cm long is attached to the prong of an electrically driven tuning fork that oscillates perpendicular to the length of the string at a frequency of 60 Hz. The mass of the string is 0.044 kg.
Question 1: What tension must the string be under if it is to be oscillating in the 4th harmonic.
Your answer must be supported by illustrations. Thanks.
