4. A student is looking at a monochromatic light source and is looking for the third bright fringe. The light has a wavelength of 625 nm and has passed through a diffraction grating with a slit separation of 2.80 x 10* m. At what angle should the student look for the third bright fringe? 5. Explain how the polarization of light is used as evidence to support the transverse wave nature of light. 6. Use the terms refraction and diffraction to complete the blanks for the two statements that follow. a. Blue light is affected more by b. Red light is affected more by ment Booklet 7 ur teacher
