Explain the formation of image by a plane mirror with the help of ray diagram for a point sized object |
|
Answer» For the ray starting from point A and travelling in a horizontal direction towards point E, the ANGLE of INCIDENCE is 0 and hence it retraces its path. Similarly, the ray starting from A and travelling towards point C follows the law of reflection. When these rays are produced backwards they appear to meet at a point E and D. Now this image is known as a virtual image. What is the difference between real and virtual IMAGES? In real image, the rays of light actually meet after reflection while in a virtual image it APPEARS to meet but not actually meet. A real image can be obtained on screen but not a virtual image.Explanation:mark me as brainleist |
