Question

5. Red light has a frequency of 4.0 X 101* hz a. Find the e speed of red light in a vacuum if its wavelength is 7.5 × 10 m. Speedt:m/s 16 b. As red light enters glass its wavelength changes to 5.8 x 10-7 m, but its frequency remains constant. What is the speed of red light in this glass? Speed: 2.32x 6 ms, m/s C. The index of refraction in a material is the ratio of the speed of light in vacuum to the speed of light in a material. What is the index of refractio of the glass in in part b? Index of refraction, n
