Question: If the intensity of light at a point of constructive interference is I, what is the intensity at a point of destructive interference?

Options:

Correct Answer: 0

Solution:

At destructive interference, the intensity is zero because the waves cancel each other out.

If the intensity of light at a point of constructive interference is I, what is the intensity at a point of destructive interference?

If the intensity of light at a point of constructive interference is I, what is the intensity at a point of destructive interference?

Step 1: Understand what constructive interference means. It occurs when two waves combine to make a wave with a larger intensity.
Step 2: Know that at a point of constructive interference, the intensity is given as I.
Step 3: Understand what destructive interference means. It occurs when two waves combine in such a way that they cancel each other out.
Step 4: Realize that when waves cancel each other out completely, the resulting intensity is zero.
Step 5: Conclude that at a point of destructive interference, the intensity is 0.

Interference of Waves – The phenomenon where two or more waves superpose to form a resultant wave, leading to constructive or destructive interference.
Constructive Interference – Occurs when waves combine to produce a wave of greater amplitude, resulting in increased intensity.
Destructive Interference – Occurs when waves combine in such a way that they cancel each other out, resulting in reduced or zero intensity.
