What happens to the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere?

Question

anonymous · Answer

In constructive interference the amplitudes add together temporarily as the waves pass each other.

anonymous · Answer

It is half than the amplitude of each wave.
It is twice than the amplitude of each wave.
It is the mean of the amplitudes of the two waves.
It is the square of the amplitude of each wave.
It is zero.

anonymous · Answer

If the wave have equal amplitudes it will be twice the amplitude.

According to the law of reflection, what is the relationship between the angle of incidence and the angle of reflection?

anonymous · Answer

The angle of reflection is twice the angle of incidence.
The angle of reflection is half the angle of incidence.
The angle of reflection is equal to the angle of incidence.
The angle of reflection is independent of the angle of incidence.
The angle of reflection is always perpendicular to the angle of reflection.
