Effects on the Image Formed by a Concave Mirror
When a bright object is placed in front of a concave mirror, an image is formed on a screen. The properties of the image formed depend on the position of the object with respect to the mirror.
Covering the Upper Half of the Concave Mirror
If the upper half of the concave mirror is covered, the following effects on the image formed will occur:
1. The Image Changes Position
When the upper half of the concave mirror is covered, the image formed by the lower half of the mirror will shift upwards. This is because the rays of light that were previously reflected by the upper half of the mirror are now blocked, and only the rays reflected by the lower half of the mirror are allowed to form the image.
2. The Size of the Image Remains the Same
Covering the upper half of the concave mirror does not change the size of the image formed. This is because the size of the image is determined by the distance of the object from the mirror and the focal length of the mirror, which remain constant even when the upper half of the mirror is covered.
3. Brightness is Reduced
When the upper half of the concave mirror is covered, the amount of light that enters the mirror is reduced. This means that the intensity of the light rays that form the image is also reduced, resulting in a dimmer image.
Conclusion
In summary, covering the upper half of a concave mirror will cause the image formed to change position and become dimmer, but the size of the image will remain the same.

The correct option is d
. that is its brightness will get reduced.it is because when we cover the upper half of the mirror it does not change or effect the position of image formed as focal lenght nd object distance remains same . however the intensity or brightness decreases
