What is thin-film interference ?

Thin-film interference is the phenomenon that is a result of lightwave being reflected off two surfaces that are at a distance comparable to its wavelength. When light waves that reflect off the top and bottom surfaces interfere with one another we see different colored patterns. During this, the light reaches the boundary between two media, and part of it gets reflected and some part gets transmitted. When the second medium is a thin film, there are two reflections occurring close together at the top and bottom boundary surfaces of the thin film. Thus, there are two waves emerging from a thin film – one wave reflected off the top surface of the film and the other reflected off the bottom surface.

How to Calculate Thin-film destructive interference in reflected light?

Thin-film destructive interference in reflected light calculator uses destructive_interference = Number*Wavelength to calculate the Destructive Interference, Thin-film destructive interference in reflected light is formed when a plane wave (parallel rays) is incident normally on a thin film of uniform thickness d then waves reflected from the upper surface interfere with the waves reflected from the lower surface. Destructive Interference and is denoted by I_d symbol.

How to calculate Thin-film destructive interference in reflected light using this online calculator? To use this online calculator for Thin-film destructive interference in reflected light, enter Number (n) and Wavelength (λ) and hit the calculate button. Here is how the Thin-film destructive interference in reflected light calculation can be explained with given input values -> 4 = 2*2.

FAQ

What is Thin-film destructive interference in reflected light?

Thin-film destructive interference in reflected light is formed when a plane wave (parallel rays) is incident normally on a thin film of uniform thickness d then waves reflected from the upper surface interfere with the waves reflected from the lower surface and is represented as I_d = n*λ or destructive_interference = Number*Wavelength. A number is a mathematical object used to count, measure, and label and Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
