Question

18. What can accurately be said about a resultant wave that displays both reinforcement and interference?

Answer 1

Answer:

Interference is a phenomenon that describes a meeting of two waves with each other. If the waves are in identical phase, they'll upgrade each other, creating a bigger capacity wave or a bigger crest and trough at that point.

If they happen to be in opposite phase, they diminish each other either fully or partially.

This is termed as destructive interference wave.Results can be brief to the exact way it is done. The results of a laboratory test are precise to demonstrate everything that influenced, or interfered with the end result.

Explanation:

Answer 2

A resultant wave which displays both interference and reinforcement means that the 'component waves' have frequencies which is different.  

EXPLANATION:

Interference takes place when two or more waves move on intersecting or coincidental paths. Interference results in the addition of amplitude in both the waves.

When two waves has same frequency and vibrate at the 'same rate' and at the 'same time', their amplitudes are said to be reinforced causing constructive interference.
