3. The equation of motion of a SHM oscillator is x=0.5msin(2πf)t, where x is in meter and t is in seconds. If the position of the oscillator is at x=0.25m and t=0.25s . what is the frequency of the oscillator ?  ​

Answer :

Answer:

f = 1/3 Hz

Explanation:

0.25 = 0.5 sin(2πf)0.25

0.5 = sin(0.5πf)

take arcsine of both sides in radians

0.52359 = 0.5πf

f = 0.52359 / 0.5π = 0.33333...
