The image formed in a concave mirror when an object is located between C and F is real, inverted, and larger than the object or magnified. Wherever the object may be between the center of curvature and focus, the concave mirror will always produce a magnified version of an object that is farther from the center of curvature. The image produced is real because light rays would converge to where the object is located.
The image is reflected, therefore it would be inverted because it reflects and flips light. It would be larger and real because it reflects whatever is facing the mirror and would be closer reflecting the curvature.
Light gates are more reliable. When using a manual stop watch, it is difficult to stop it at an exact time. A light gate is able to detect when an object passes through a 'gate' with the infrared transmitter and receiver.
