Question

Find the focal length of a convex mirror using convex lens

Answer 1

Answer:

To determine focal length of a convex lens

Place the holder with the screen on the bench. The position of the screen should be such that the sharp image of the distant object is obtained on it. The difference between the position of the lens and the screen is equal to the focal length of the given convex lens.

Answer 2

The focal length of a convex mirror using convex lens.

Explanation:

• The focal length of a convex mirror can be determined by placing a convex lens between the object and the convex mirror.
• An image can be obtained with  a convex lens next to an object when the convex mirror reflects the rays along the same path.
• If the ray falls on the mirror, it is normal.
• the focal length of the mirror using the equation$f = R/2.$
• The distance from the lens to the focal point is called the focal length.
• The focal length of a convex mirror is half of its radius of curvature.
• The focal length of a double convex lens is given by the formula $(1/v) + (1/u) = (1/f),$ Place the convex lens in such a position that sunlight is perpendicular to the lens.
