For light reflected off the thin film (as shown in the figure), where the film's index of refraction n = 1.46, and where the rays are close to normal incidence, what is the minimum film thickness that will result in a maximum reflected intensity for a wavelength of light A = 650 nm? Note the units of nm: 1 nm = 10-9 m. tmin = If this film is increased in thickness, what is the minimum thickness (but greater than your first answer) that results in a minimum reflected intensity for the same wavelength of light? nm nm

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
