5 What is the delta T ?
5) Two identical sinusoidal waves with frequency of 20 Hz travel in the same direction at the same speed.
The two waves originate from the same point but with a time difference At. The amplitude of the
resultant wave is Ares = AV3. The minimum possible time difference between the starting moments of
the two waves is, At =:
(a) 1/120 sec
(b)0.477 sec
(c) 1/80 sec
(d)0.716 sec
