To form the image on the object itself, how should we place the object in front of a concave mirror ? Explain with a ray diagram.
To form the image on the object itself, the object should kept at centre of curvature of a concave mirror.
- An object AB has been placed at the centre of curvature ‘C’ on the concave mirror.
- A ray of light AD which is parallel to principle axis passes through the focus ‘F after reflection as DA’.
- A ray of light passing through the focus of the concave mirror becomes parallel to the principle axis after reflection.
- Here AE ray passing through focus and reflected as EA’.
- The reflected rays DA’ and EA’ meet at A’ point. So the real image formed at point A of the object.
- To get couple image A’B’ perpendicular to the principle axis.
- Thus A’B’ is the real image of the object AB.
