An object in simple harmonic motion is observed to move between a maximum position and a minimum position. the minimum time that elapses between the object being at itsmaximum position and when it returns to that maximum position is equal to which of the following parameters? a) frequencyb) angular frequencyc) periodd) amplitudee) wavelength

c

Explanation:

When an object is performing simple harmonic motion then time period is given by measuring the time period take by object to return its  initial position.

Thus we can say that it also valid for maximum position thus period is the correct is answer for this problem.

Time Period of oscillation for spring mass system is

snell's law

refractve index = sin incidence / sin refraction
