Question

When two or more waves are at the same place at the same time, the resulting effect is calleda. a standing wave.b. a Doppler wave.c. a shock wave.d. interference.e. a period

Answer 1

Answer:

The correct option is;

d. interference

Explanation:

Interference is the result of the superposition of waves.

Superposition of waves occurs when two or more waves are present at a point.

When we superimpose two or more waves are at the same place at the same time, the resulting amplitude is the sum of the amplitude of the individual waves, resulting in a similar wave with a larger amplitude.

Where we have the resultant of the superposition wave have a larger amplitude than any of the included individual wave, it is termed constructive interference

However, when the amplitude of the resultant superposition wave due to the sum of two or more waves is less than than any of the included wave, or zero, we have destructive interference.

Answer 2

Answer: option D

Explanation: The combination of 2 waves to produce a resultant effect at a point is known as interference.

If the waves are in the same direction, the resultant effect is of a larger magnitude, this is called constructive interference which is still a progressive wave.

If the resultant effect brings about cancellation of both waves, we have a destructive interference which forms a standing wave.
