Two waves with Amplitude of 75 units and 74 units arrive at a point in a medium simultaneously. If the two waves are out of phase with each other what is the resultant amplitude of the wave

Resultant amplitude = 1 unit.

Explanation:

The amplitude of a wave is its maximum displacement during propagation.

Since the two waves are out of phase, the resultant amplitude can be determine by;

Resultant amplitude, =

                                        =

                                        = -  

where is the phase difference.

Given that: = 75 units, = 74 units, so that;

= 75 - 74

     = 1

The resultant amplitude of the two wave when out of phase is 1 unit.
