Question

Answer the following questions with yes (Y) or no (N); e.g., enter YYYYY.

PLEASE EXPLAIN ALL

1. 
   
2. Does an object placed exactly at the focus of a concave mirror form an image?
3. Can a convex mirror form a real image?
4. Does the image formed by a convex mirror always lie between the mirror and its focus?
5. When an object is placed between the concave mirror's focus and its centre of curvature, is its image always real and inverted?
6. Can a plane mirror only form real images?

Answer 1

The image can be formed in case of convex mirror. Hence, the answer is N Convex mirror can form a real image when the object is virtual. Hence, the answer is Y. 1V When the object is placed at infinity, then the image is formed at the focus. When the object is placed any point between pole and infinity, then the image is formed in between the mirror and focus. Hence, the answer is Y v) When the object is placed in between the focus and center of curvature, then the image is formed beyond the center of curvature. In this case, the image is enlarged, real, and inverted. Hence, the answer is Y vi) Plane mirror can produce virtual image when the object is real. It always produces virtual images. Hence, the answer is N.
