. A beam of white light goes from air into water at an incident angle of 75.0°. At what angles are the red (660 nm) and violet (410 nm) parts of the light refracted? Are the angles going to be different if the light strikes a crown glass slab, instead of water? Explain.

The figure below shows two unknown devices, each of which separates (disperses) white light into its spectrum. The positions of the two wavelengths are shown on each screen. Two optical devices that can produce cases A and B (respectively) are Case A ? Case B ? 2.700 nm 2400 nm 2400 nm 2.700 nm OA. a concave mirror and a convex lens B. a ray box and a prism C. a transmission grating and a prism OD. a transmission grating and a ray box

An Optical Spectrometer. You and your team are tasked with characterizing an equilateral, triangular prism to be used in an optical spectrometer. An optical spectrometer contains a dispersive element (in this case, the prism) that separates an incoming beam of light into its constituent wavelengths (or colors), and a photocell that measures the intensity of each color (wavelength) by measuring the intensity of the dispersed light as a function of angle. The index of refraction of the prism material you are using depends on the wavelength as n(A)=(1.111 x 104 nm¹) A (nm) + 1.609 An incident beam of white light impinges on the surface (see drawing) at an angle of 42.2 degrees below the normal. The prism is in air (n = 1.000). Normal Ꮎ Red (660 nm) Violet (410 nm) (a) Relative to the prism base (i.e., the horizontal in the drawing), at what angle does red light (A-660.0 nm) emerge on the opposite side? (b) Relative to the prism base (i.e., the horizontal in the drawing), at what angle…
