B.
If two out-of-phase waves arrive simultaneously at a point, their amplitudes add up.
C.
If two in-phase waves arrive at a point one after another, their amplitudes add up.
D.
If two out-of-phase waves arrive at a point one after the other, their amplitudes adds up.

Respuesta :

Answer;

A. If two in-phase waves arrive simultaneously at a point, their amplitudes add up.

Explanation;

  • According to the principle of superposition, when two waves of the same kind meet at a point in space, the resultant displacement at that point is the vector sum of the displacements that the two waves would separately produce at that point.
  • Interference involves the superposing of two or more coherent waves to produce regions of maxima and minima in space, according to the principle of superposition.
  • Interference may be constructive or destructive; Constructive interference occurs when two or more waves arrive at the screen in phase with each other, such that the amplitude of the resultant wave is the sum of the amplitude of the individual waves.
  • Destructive interference occurs when two or more waves arrive out of phase with each other and resultant wave has minimum amplitude.
