    Light is normally incident on one face of a 23 o flint-glass prism. Calculate the angular separation (deg) of red light (λ = 650.0n m) and violet light (λ = 450.0n m) emerging from the back face. Use nred = 1.644 and nviolet = 1.675. (See the figure. Note that the angle of the prism may be different in your problem.) 8. (Violet) - (Red) Bodeg Red 30deg Violet Figure 24.33

    A beam of white light goes from air into water at an incident angle of 79 degrees. At what angles are the red (660 nm) and violet (410 nm) parts of the light refracted? The difference between the angles of refraction of two colors is_______ degrees. I have solved and gotten 48 degrees for RED and 47 degrees for VIOLET.

     A beam of white light is incident on the surface of a diamond at an angle θa.(Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. The indices of refraction in diamond are Tred = 2.410 for red light and Mblue = 2.450 for blue light. The surrounding air has Tair = 1.000. Note that the angles in the figure are not...

    The Ocrit angle is= 24.09 degrees A beam of white light is incident on the surface of a diamond at an angle 02. (Figure 1) The index of refraction actually depends on the light's wavelength, so the different colors that comprise white light will spread out as they pass through the diamond (like in a prism). The index of refraction in diamond is nblue = 2.450 for blue light while the indices of refraction for the lower frequency colors are...
