Question : 41

Total: 91

A wave in a string has an amplitude of 2 cm. The wave travels in the +ve direction of x axis with a speed of 128 m/sec and it is noted that 5 complete waves fit in 4 m length of the string. The equation describing the wave is

y = (0.02) m sin (15.7x - 2010t)
y = (0.02) m sin (15.7x +2010t)
y = (0.02) m sin (7.85x - 1005t)
y = (0.02) m sin (7.85x + 1005t)
