प्रश्न
Draw a ray diagram to show the formation of image of an object placed on the principal axis of a convex mirror. State the position, size and nature of the image. What happens to the image as the object is moved away from the mirror?
उत्तर
OBJECT PLACED IN FRONT OF CONVEX MIRROR :
Place the object anywhere in front of convex mirror image formed is
- Between pole and focus ← position.
- Diminished ← size.
