True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.
