The amplitudes and phase differences for four pairs of
Chapter , Problem 6(choose chapter or problem)
The amplitudes and phase differences for four pairs of waves of equal wavelengths are (a) 2 mm, 6 mm, and 7Trad; (b) 3 mm, 5 mm, and 7Trad; (c) 7 mm, 9 mm, and 7Trad; (d) 2 mm, 2 QUESTIONS 437 mrn, and 0 rad. Each pair travels in the same direction along the same string. Without written calculation, rank the four pairs according to the amplitude of their resultant wave, greatest first. (Hint: Construct phasor diagrams.)
