In a thin-film light reflects

WebThin film interference refers to the phenomenon where interference of the light waves that get reflected by the upper and lower sides of a thin film occurs. This interference is capable of either increasing or reducing the light reflected from the film. How does Thin film interference happening ? Web8 years ago. Consider the equation 2t = m/\ ( /\ = wavelength) ,which is applicable for constructive interference if there no or n/\ times change in the path difference. Now by rearranging the equation, we get "t = m/\ / 2" . So, as it is clearly seen now , "m" is merely a parameter which determines whether constructive or destructive ...

WebThe following diagram helps in explaining when you see fringes in a thin film When ray 1 hits the surface on the top, some of the light is partially reflected as seen in ray2 and the rest is refracted as seen in ray 3. When ray 3 hits the bottom surface, some of it is reflected as seen in ray 4 and the rest is refracted as seen in ray 6. WebThis is known as thin-film interference, because it is the interference of light waves reflecting off the top surface of a film with the waves reflecting from the bottom surface. To obtain a nice colored pattern, the thickness …
