Regents Physics Dale. Homework # 12 - Dispersion of Light Handout Problems: 1. As shown in the reference table, the index of refraction of Lucite is 1.50 for light of frequency 5.09 x 1014 Hz (yellow). Explain why it must be more than 1.50 for blue light. 2. Which color of light has the greatest (a) frequency; (b) wavelength? 3. Calculate the speed of light in Zircon. 4. The speed of light in plastic is 2.0 x 108 m/s. What is the index of refraction of the plastic? 5. Light of wavelength 6.40 x 10 7 meter traveling in Quartz enters diamond. Calculate the new wavelength of the light in diamond. 6. What happens to the (a) speed, (b) wavelength and (c) frequency of light as it travels from the Quartz into the diamond
