The index of refraction for violet light in silica flint glass is 1.66 and that for red light is 1.62. What is the angular dispersion of visible light passing through an equilateral prism of apex angle 60.0° if the angle of incidence is 56.0°? (See figure. The index of refraction for air is 1.00.)

A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction?   Calculate to 1decimal.

A light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 44.20°. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light). Find the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths.

A light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 56. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light).

A ray of white light traveling through air enters a triangular prism that has an index of refraction of 1.511 for the red end of the spectrum and 1.537 for the violet end and an apex angle of 64.8 degrees. If the ray has an angle of incidence of 46.3 degrees with respect to the normal of the interface boundary, what is the angular separation between the red and violet ends of the spectrum upon exiting the prism? Measure this in degrees to 2 decimal places.

A certain kind of glass has an index of refraction of 1.660 for blue light of wavelength 420 nm and an index of 1.620 for red light of wavelength 690 nm. If a beam containing these two colors is incident at an angle of 30.0° on a piece of this glass, what is the angle between the two beams inside the glass?

The index of refraction for violet light in silica flint glass is 1.67 and that for red light is 1.62 . What is the angular dispersion of visible light passing through an equilateral prism of apex angle 60.0o if the angle of incidence is 47.00o?
