Geometric Optics
64- Real images are always inverted.
65- Virtual images are always upright.
66- Diverging lens (concave) produce only small virtual images.
67- Light rays bend away from the normal as they gain speed and a longer wavelength by entering a slower (n) medium {frequency remains constant}.
68- The focal length of a converging lens (convex) is shorter with a higher (n) value lens or if blue light replaces red.
