Light travels in a straight line at a constant speed of 300,000 meters per second. What is the acceleration of light?Equations of Motion:Newton gave three equations of motion for a moving object which shows the relation between acceleration, initia...
Ray optics is based on the assumption that light travels in a straight line. Diffraction effects (observed when light propagates through small apertures/slits or around small obstacles) disprove this assumption. Yet the ray optics assumption is so commonly used in understanding location and several ...

A ray is defined as the path of energy propagation in the limit of wavelength tending to zero. It travels in a straight line and defined as the path of energy propagation.
You can see around corners. Light travels in a straight line. It reflects off the mirrors, which enables you to see around corners. That is a good start for a study of Light Energy for Kids! How do you study light energy with kids?
