For a piece of glass n(red)= 1.635 and n(blue)= 1.689. The respective wavelengths are 680nm (red) and 430nm (blue). Find the angle between these two colors of light in the glass if they were originally in a white light beam in air incident on the glass at an angle of 44.
For water n(red)= 2.332 and n(blue)=1.340. What are the underwater angles of refraction for the red and blue components of a white light beam in air incident at an angle of 82 on a water surface?
The level of water in a clear, colorless glass is easily observed with the naked eye. The level of liquid helium in a clear glass vessel is extremely difficult to see with the naked eye. Explain. (hint: the index of refraction of liquid helium is close to that of air.)
thank you! :)
