Question

What is interference?
Give an example of a constructive interference and an example of destructive interference.
What happened to cause the waves to weaken?

Answer 1

Destructive Interference: Noise canceling headphones (sound waves), 'dead spots' from speakers (sound waves), anti-glare coatings on glass (light), diffraction gratings (light), spectroscopy (light)

Constructive Interference: Rogue waves (ocean waves), double slit experiment (constructive and destructive), loud areas from speakers (sound waves).

Answer 2

Interference:
whenever two or more waves are superimposed upon each other then there occurs redistribution of light. This phenomenon is called Interference.

Constructive Interference:
Take an example of a sinusoidal wave.
When crust of one wave falls on the trough of the other wave and vice versa, then we say that it is a constructive interference. And due to this, bright light or simple light produces.

Destructive Interference:
When crust of one wave falls on the crust of the another wave or when the trough of the first wave falls on the trough of the other wave, there occurs destructive interference. Destructive Interference causes no production of light.

Answer 3

Definition: The variation of wave amplitude that occurs when waves of the same or different frequency come together

Answer 4

As for causing waves to weaken, are you referring to light waves or sound waves?

Answer 5

waves in water

Answer 6

Or ocean waves?

Answer 7

Ok sorry about that give me one minute.

Answer 8

As the wave travels further distances it weakens, it also weakens because while it's traveling, it is enduring much resistance.
