Examples of Destructive Interference

Destructive vs Constructive Interference

Following are some examples of destructive interference:

Anti-reflective coatings: These coatings on lenses or glasses use destructive interference to cancel out specific wavelengths of light, reducing reflection and glare.

Diffraction gratings: These gratings utilize destructive interference to produce specific diffraction patterns that split light into its constituent colors, as seen in rainbows or holograms.

Noise-canceling headphones: These headphones use microphones to pick up ambient noise and generate sound waves with the opposite phase, leading to destructive interference and noise cancellation.

Soundproofing materials: These materials often contain structures designed to resonate with and destructively interfere with specific sound frequencies, reducing noise transmission.

Destructive Interference

Destructive Interference occurs when two waves of the same frequency meet and overlap in a way that causes their amplitudes to cancel each other out, resulting in a wave with zero amplitude at specific points.

Interference occurs when two waves meet. This phenomenon includes superimposing the waves into a wave that can either be bigger, smaller, or the same magnitude. Wave interference can be categorized into two different types i.e., Constructive and Destructive Interference. In this article, we will discuss the nature of interference and describe destructive interference.
