- When white light illuminates an oil film on water and the reflected light is viewed perpendicular to the surface of the water, no green light at 512 nm is reflected but there is a strong presence of red light with a wavelength of 640 nm. Determine the thickness of the oil film. Take the index of refraction of oil to be 1.28.Light that is from a helium-neon laser and has a wavelength of 633 nm passes through a 0.18-mm-diameter hole and forms a diffraction pattern on a screen 2.15 m behind the hole. Calculate the diameter of the central maximum.Light of wavelength 430 nm in water illuminates a glass (n = 1.5) wedge submerged in water (n = 1.33). If the distance between successive bright fringes is 6 mm... Find the change in thickness of the glass between these fringes: 215 nm; And the angle of the wedge radians.
- White light is directed perpendicular to an oil film (n = 1.45). Calculate the minimum non-zero thickness of the film required to eliminate blue (450nm) reflections.Mourning doves have a small batch of iridescent feathers.
