Concave | MCQs

Explanation

In a concave mirror, the image size depends on the position of the object.

As the object moves closer to the mirror, the image size increases, and as it moves away, the image size decreases.

Explanation

Concave lenses are also known as diverging lenses, as they spread out light rays and diverge them away from a single point.

Explanation

When an object is placed far away from a concave mirror, its image will be:

• Real (a projected image that can be seen on a screen)
• Inverted (upside down)
• Smaller in size than the object (reduced)

Explanation

When an object is placed very close to a concave mirror, its image will be:

• Virtual (not a real image that can be projected onto a screen)
• Upright (not inverted)
• Larger in size than the object (magnified)

Explanation

• A Concave Mirror has a curved reflecting surface that bulges inward, like the front side of a spoon.
• This type of mirror is used in telescopes, solar concentrators, and other applications where light needs to be focused.
