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 coloured patterns. During this, the light … See more An important consideration in determining thin-film interference is also by knowing the source of the light. A source could be a monochromatic or broadband source. Monochromatic source results in interference patterns … See more The phase difference is the difference in phase angle between two waves. Path difference is defined as the difference in actual distance travelled by the two waves. The phase angle is the part of one complete wave cycle … See more 1. A thin film of soap solution is illuminated by white light at an angle of incidence i = sin-1(4/5). In the reflected light, two dark consecutive overlapping fringes are observed corresponding to wavelengths 6.1 x 10-7 m and 6.0 … See more When we take a soap bubble, light waves travel through the air and hits the soap film. If we look at the refractive index of air it is 1(nair= 1) whereas the film will have an index larger than … See more WebMar 8, 2024 · Thin films have a great impact on the modern era of technology.
