State any two observations from everyday life which show that light travels in straight lines.
Dear Student ,
Two observations which proves that light travels in straight path are as follows:
1. Formation of Shadow: shadows are formed when some light rays continue to travel in straight lines while other rays are stopped by an object.
2. Pin hole camera: Formation of image in pin hole camera
Hope this helps you.
