CBSE Class 11-science Physics Waves
Behaviour of Progressive Waves
When we have one fixed end and one free end : An odd number of 1/4 wavelengths fit inside the medium and the overtones are odd multiples of the fundamental frequency
Beat frequency: Difference of frequencies of the two sources.
During the beats, the resultant sinusoidal wave has fluctuating amplitude that causes the varying loudness as a function of time.
