(a) Sodium vapor light averaging 589 nm in wavelength falls on a single slit of width 7.50 µm. At what angle does it produce its second minimum?
(b) What is the highest-order minimum produced?
What is the index of refraction of a material for which the wavelength of light istimes its value in a vacuum? Identify the likely substance.
(a) If a single slit produces a first minimum at \({\rm{14}}{\rm{.5^\circ }}\),at what angle is the second-order minimum? (b) What is the angle of the third-order minimum? (c) Is there a fourth-order minimum? (d) Use your answers to illustrate how the angular width of the central maximum is about twice the angular width of the next maximum (which is the angle between the first and second minima).
Show that when light passes from air to water, its wavelength decreases to\({\rm{0}}{\rm{.750}}\)times its original value.
