• Periodic but not SHM

An object oscillates along a straight line with SHM of frequency 30 Hz. If the distance between the two extreme points of the motion is 0.020 m, what is the maximum acceleration of the object?

A body is performing SHM with maximum displacement of 0.1 m and frequency of 2.0 Hz. If the displacement of the body is zero at t=0, which of the following equations describes the motion of the body?

• 10.0 m

• 6.0 m

• 1.0 m

• 0.1 m

The principle of superposition states that

• The total energy of the resultant wave is the sum of the energy carried by the individual wave

• Two stationary waves superimpose to produce a progressive wave.

• The frequency of the resultant wave is the difference between the frequencies of the individual waves.

• The displacement at a point of the resultant wave is the sum of the displacement of the individual waves acting at that point.
