A soap fi lm (n = 1.33) is 375 nm thick and coats a fl at piece of glass (n = 1.52). Thus, air is on one side of the fi lm and glass is on the other side, as the fi gure illustrates. Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels through air and strikes the fi lm nearly perpendicularly. Concepts: (i) What, if any, phase change occurs when light, traveling in air, refl ects from the air–fi lm interface? (ii) What, if any, phase change occurs when light, traveling in the fi lm, refl ects from the fi lm–glass interface? (iii) Is the wavelength of the light in the fi lm greater than, smaller than, or equal to the wavelength in a vacuum? Calculations: For what wavelengths in the range of 380 to 750 nm does constructive interference cause the fi lm to look bright in refl ected light? Apr 25 2022 08:12 PM
