## 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 transmitted light?

Thin-film destructive interference in transmitted light calculator uses Destructive Interference=(Number A+1/2)*Wavelength to calculate the Destructive Interference, Thin-film destructive interference in transmitted light is formed when a film is placed in the air the wave reflected from the upper surface (from a denser medium) suffers a sudden phase change of π, while the wave reflected from the lower surface suffers no phase change. In this case, constructive and destructive interferences are formed. Similarly, Interference also occurs in transmitted light. Destructive Interference and is denoted by Id symbol.

How to calculate Thin-film destructive interference in transmitted light using this online calculator? To use this online calculator for Thin-film destructive interference in transmitted light, enter Number A (No. A) and Wavelength (λ) and hit the calculate button. Here is how the Thin-film destructive interference in transmitted light calculation can be explained with given input values -> 5 = (2+1/2)*2.

### FAQ

What is Thin-film destructive interference in transmitted light?
Thin-film destructive interference in transmitted light is formed when a film is placed in the air the wave reflected from the upper surface (from a denser medium) suffers a sudden phase change of π, while the wave reflected from the lower surface suffers no phase change. In this case, constructive and destructive interferences are formed. Similarly, Interference also occurs in transmitted light and is represented as Id=(No. A+1/2)*λ or Destructive Interference=(Number A+1/2)*Wavelength. Number A is a number 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.
How to calculate Thin-film destructive interference in transmitted light?
Thin-film destructive interference in transmitted light is formed when a film is placed in the air the wave reflected from the upper surface (from a denser medium) suffers a sudden phase change of π, while the wave reflected from the lower surface suffers no phase change. In this case, constructive and destructive interferences are formed. Similarly, Interference also occurs in transmitted light is calculated using Destructive Interference=(Number A+1/2)*Wavelength. To calculate Thin-film destructive interference in transmitted light, you need Number A (No. A) and Wavelength (λ). With our tool, you need to enter the respective value for Number A and Wavelength and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Destructive Interference?
In this formula, Destructive Interference uses Number A and Wavelength. We can use 1 other way(s) to calculate the same, which is/are as follows -
