A stretched wire 0.5 m long is made to vibrate in two different modes as shown in diagram (A) and (B) given below :
a) If the wavelength of the wave produced in mode (A) is 1 m, what is the wavelength of the wave produced in mode (B) of the following diagram?
b)In which case is the note produced louder? Give a reason for your answer.
c) In which case is the pitch of the note produced higher? Give a reason for your answer.
