State True/False for the following: a)The inverse of the focal length (f) of a thin lens surrounded by air is given by the lens-maker's equation. b)The ratio of the object height to image height is the lateral magnification due to a mirror or lens. c) A spherical mirror has a focal length of +10.0 cm. For an object located at 25.0cm Infront of the mirror, The image produced has a magnification of about - 0.667. d) A fish is swimming at a depth of 1.50 m below the surface of a pond. Hence the apparent depth of the fish as viewed from directly overhead is about 1.128 m below the water surface. e) A diverging lens has a focal length of 10.0 cm. For an object placed 15.0 cm in front of the lens, the image formed is virtual, smaller than the object size, and upright
