Answer:
Interference
Explanation:
When two waves of same frequency and constant phase difference super impose at a point on the screen then due to their superposition we will get different intensity of light at different positions of the screen
This phenomenon of redistribution of energy is known as interference of light.
So at the position of screen where the light intensity is maximum on the screen is known as constructive interference while the positions on the screen where it will get minimum intensity on the screen is known as destructive interference of the light
So correct answer would be
Interference
The interference principle is responsible for alternating light and dark bands when light passes through two or more narrow slits.
What is Interference?
The phenomenon in which two or more waves combine to generate a new wave with a larger, smaller, or equal amplitude. It depends on the alignment of the peaks and troughs of the overlapping waves.
When two or more waves collide, this is known as interference. They may add up, or they may partially or completely cancel each other,
When two waves with the same frequency. We will see varying intensities of light at different points on the screen owing to their superposition.
Hence interference principle is responsible for alternating light and dark bands when light passes through two or more narrow slits.
