Correct Answer - Option 1 : real, inverted and same in size
CONCEPT:
-
Concave mirror: The mirror in which the rays converge after falling on it is known as the concave mirror.
- Concave mirrors are also known as converging mirrors.
- The focal length of a concave mirror is negative according to the sign convention.
The mirror formula is given by:
\(\frac{1}{v}+\frac{1}{u}=\frac{1}{f}\)
where v = distance of image; u = distance of object; f = focal length of mirror
The Magnification of mirror (m) is given by:
\(m=\frac{f}{f-u}\)
CALCULATION:
- The object is at the center of the curvature of the concave mirror so the image will form at the same place.
- The image formed will be real and inverted.
\(m=\frac{-20}{-20-(-40)}\)
m = - 1
Image is formed of equal size, real and inverted.
