This is called reflection.<\/p>\n<p>Question 14.<br \/>\nCan you see the light reflected by an object?<br \/>\nAnswer:<br \/>\nWe can see the reflected light only when light falls on the objects like mirror.<\/p>\n<p>Question 15.<br \/>\nHow does mirror differ from a glass sheet?<br \/>\nAnswer:<br \/>\nA mirror reflects light falling on it.
