Question

Optics 7. The optical path length is just the actual distance a ray of light travels a) True b) False 8. The index of refraction does not affect the velocity of propagation. a) True b) False 9. For a prism to disperse white light into many colors it must somehow have different index of refractions for every color a) True b) False 10. Consider a ray of light going from ni to i. If n > n the ray brakes towards the surface normal a) True b) False 11. Consider a ray of light going from ni to a different na. You can expect that the wavelength in n2 will be necessarily different. a) True b) False 12. Consider a ray of light going from ni to a different n2. You can expect that the frequency in n2 will be necessarily different. a) True b) False 13. Given the equation n. The letter c stands for the velocity of light in vacuum. a) True b) False 14. In specular reflection incident angle can not be equal to the reflected angle. a) True b) False 4 of 8
