A narrow beam of light containing red (660 nm) and blue (470 nm) wavelengths travels from air through a 1.60 cm thick flat piece of crown glass and back to air again. The beam strikes the glass at a 35.0° incident angle.
(a) At what angles do the two colors emerge from the glass?
(b) By what distance are the red and blue separated when they emerge?
Please show detailed work so I can learn how to do this.
