Question
Two coherent waves of amplitude 3mm and 4mm superimpose with a phase difference of 90°. What is the amplitude of resultant wave?
Solution
Amplitude of first wave = 3mm
Amplitude of second wave = 4 mm
Resultant amplitude is given by, R =
That is,
R =
Amplitude of second wave = 4 mm
Resultant amplitude is given by, R =
That is,
R =
