Subjective Type

Draw a ray diagram to show the formation of image of an object placed beyond the center of curvature of a concave mirror. State the position, size and nature of the image.

Solution

OBJECT PLACED BEYOND C :
Image is formed: A real, inverted and smaller image is formed between the center of curvature and focus
Position: between C and F.
Size smaller than the object.
