Question

+2+10-1-2When the centers of the two pulses meet at point X, theamplitude at the center of the resultant pulse will bea + 1 unitboC + 2 unitsd -1 unite none of the above

Answer 1

The amplitude of wave A is +2 units and the amplitude of wave B is -1 units.

The amplitude of resultant pulse of the pulse can be calculated as,

`\begin{gathered} y=+2-1 \\ =+1 \end{gathered}`

Therefore, the amplitude of resultant wave is +1 unit which means option (a) is correct.
