Question 1 Report

After reflection from the concave mirror, rays of light from the sun converges
Answer Details
A concave mirror is a spherical mirror with a reflecting surface that is curved inward. When parallel rays of light fall on a concave mirror, they are reflected in a way that depends on the distance between the mirror and the object, as well as the curvature of the mirror. If the object is located beyond the focal point of the concave mirror, the reflected rays will converge at a point between the focal point and the radius of curvature of the mirror. This point is known as a real image. However, if the object is located at a distance less than the focal length from the mirror, the reflected rays will diverge and not form a real image. Instead, they will form a virtual image that is located behind the mirror. In the case of the question, if rays of light from the sun fall on a concave mirror, and the mirror is positioned such that the sun's rays are parallel to its axis, then the reflected rays will converge at the focal point of the mirror. This is because the focal point is the point at which parallel rays of light, such as those from the sun, converge after reflection from the concave mirror. Therefore, the answer to the question is: "After reflection from the concave mirror, rays of light from the sun converge at the focus." In conclusion, the position of the object and the distance between the object and the concave mirror determine the nature of the image formed by the reflected rays of light. When the object is located at a distance greater than the focal length, a real image is formed that is inverted and smaller than the object. When the object is located at a distance less than the focal length, a virtual image is formed that is upright and larger than the object.
