Question

One benefit of pass by address is that it allows multiple changes to be made in a function and to have those changes available in the calling function.

a) True
b) False

Answer 1

The statement is false because waves do not need to be precisely aligned for their amplitudes to affect each other, as interference can occur with any phase difference.

Step-by-step explanation:

The statement that the amplitude of one wave is affected by the amplitude of another wave only when they are precisely aligned is false. In the phenomenon known as interference, waves can affect each other's amplitude even when they are not perfectly aligned. The degree of alignment, known as the phase difference, influences the resultant amplitude, but it does not need to be perfect for interaction to occur. When two waves meet, they superpose, and the resulting wave is a combination of the two original waves' amplitudes. This superposition can result in constructive interference, where the amplitudes add, or destructive interference, where the amplitudes subtract, but neither requires precise alignment.
