A string with a length of 0.5 meters is vibrating with a frequency of 100 Hz and it forms a standing wave at the fundamental mode with a velocity of 100 m/s. If the frequency at which the string vibrates is increased forming a standing wave at the fourth harmonic (n = 4) but the velocity of the wave stays the same
A) What is the new wavelength of the standing wave?
B) What is the new frequency of vibration on the sting?
