How does the image distance (di) of a convex lens compare with the image distance of a concave lens? a. the image distance of the convex lens is positive, and that of the concave lens is negative. b. both are negative for a virtual image. c. both are positive for a virtual image d. the image distance of the convex lens is negative, and that of the concave lens is positive.

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
