A coating is being applied to reduce the reflectivity of a pane of glass to light with a frequency of 5.65 1014 Hz that is incident normally on the pane. If the material has an index of refraction of 1.42 and the glass has an index of refraction of 1.537, what is the minimum thickness the coating should have in nanometers? Please keep one decimal place in your answer. (c = 3.00 108 m/s) A monochromatic light of 660-nm wavelength shines on a single slit and forms a diffraction pattern with the first minimum at an angle of 33.0 from central maximum, . The same slit, illuminated by a new monochromatic light source, produces a diffraction pattern with the second minimum at a 58.0 angle from the central maximum. What is the wavelength of this new light in nanometers? Please give your answer with no decimal places.
