Concept

Problem: A beam of white light is incident on a triangular glass prism with an index of refraction of about 1.5 for visible light, producing a spectrum. Initially, the prism is in a glass aquarium filled with air, as shown. If the aquarium is now filled with water, with an index of refraction of 1.3, which of the following is true? 1. The spectrum produced has greater separation between red and violet than that produced in air. 2. A spectrum is produced, but the deviation of the beam is opposite to that seen in air. 3. The spectrum has the same separation between red and violet as that produced in air. 4. Violet light will not emerge from the prism. 5. The intensity of the light emerging increases. 6. There is no light seen coming out of the prism. 7. The spectrum produced has less separation between red and violet than that produced in air. 8. The positions of red and violet are reversed in the spectrum. 9. No spectrum is produced. 10. Red light will not emerge from the prism.
