Question 1:

Which of the following statements about concave mirrors is true?

Explanation: Concave mirrors can form both real and virtual images depending on the position of the object. The images can be either upright or inverted. The focal length of a concave mirror is negative, indicating its ability to converge parallel rays of light.

Question 2:

When an object is placed between the focal point and the center of curvature of a concave mirror, the image formed is:

Explanation: When an object is placed between the focal point and the center of curvature of a concave mirror, a virtual and upright image is formed.

Question 3:

Which of the following lenses can converge parallel rays of light to a point?

Explanation: A convex lens has the ability to converge parallel rays of light to a point. It is also known as a converging lens.

Question 4:

The lens formula is given by:

Explanation: The lens formula is given by 1/f = 1/v + 1/u, where f is the focal length, v is the image distance, and u is the object distance.

Question 5:

When an object is placed between the optical center and the focal point of a convex lens, the image formed is:

Explanation: When an object is placed between the optical center and the focal point of a convex lens, a virtual and upright image is formed.
