Question
The vertical displacement of a string is given by y(x, t) = (6,00 mm) cos (3.25 m^-7) x = (7.22 s^-1) f. What is the period of the wave? 7.22 s 0.870 s 1.93 s 0.139 s 0.308 s A wave has an amplitude 20.0 cm, a wavelength 3.00 m, and the wave travels 60.0 m in 12.0 s. What is the frequency of the wave? 8.33 Hz 0.500 Hz 250 Hz 150 Hz 1.67 Hz Waves travel along a 100 m length of string with a mass of 56 g, which is hold by a of 75 N. What is the speed of the wave? 37 m/s 0.37 m/s 3.7 m/s 370 m/s 3700 m/sExplanation / Answer
here,
1)
the angular frequency , w = 7.22 rad/s
the time period of the wave , T = 2 * pi /w
T = 2 * pi /7.22 s
T = 0.87 s
the time period of the wave is 0.87 s
