Question
Now, consider a nail l Now, consider a nai lying near a mirox, as in the picture below.The picture shows a tup ven of the nait and the mirror.) Use the law of reflection to determine the direction of the veflected ef the nail and the mirror.) Use the law of reflection to determine the direction of the refectea ying near a mirror, as in the picture below a he picture shows. up from the nail for S or 6 rays from the nail ra Top view 1. When the reflected rays enter your eye, where do they appear to be coming from 2. Why do you see an image of the nail at a point behind the mirror? 3. Is there light at the point of the image? Ils there light coming from the image?Explanation / Answer
1) The rays appear to coming from the surface of mirror. That's why we get a virtual and erect image.
2) The light emanates from an object in a variety of directions . Some of these rays reaches the mirror according to the law of reflection. Each one of these rays of light CAN BE EXTENDED BACKWARDS BEHIND THE MIRROR WHERE THEY WILL INTERSECT AT A POINT ( THE IMAGE POINT ). Any person who is positioned along the line of one of these reflected rays can sight along the line and view the image.
3) As the image is virtual and erect image formed by the plane mirror , it appears to coming from a point behind the mirror but really the won't meet. So the light may not be there at image point but appears to light be there.
The light appears to coming from the image but really it is not coming from the image.
4) The object distance of the nail is equal to image distance of the nail as shown in the above fig.
( practically we can prove it ).
