WebApr 30, 2024 · Since, when a parallel beam of ray is incident on a convex lens then all the emerging ray converges as shown in fig.10.7. Due to which convex lenses are also called as converging lenses. Hence, ... Rays from Sun converge at a point 15 cm in front of a … WebAnswer. Sun is at infinite distance from the surface of the earth. Now light rays from sun rays after reflection from concave mirror will converge at focus. It is given that sun rays converge at 15 cm. So, focal length of the mirror = f = 15 cm. In case of a concave mirror, the size of image and object will be same if the object is placed at 2f.

WebFeb 21, 2024 · In the problem, it is given that the sun rays converge at 15 cm. So, the focal length of the mirror = f = 15 cm. In the case of a concave mirror, the size of the image and object will be the same if the object is placed at 2f. ∴. In this case, the object must be placed at 2f. So substituting the value of f = 15 cm, we get. Object distance =2 ... WebRays from Sun converge at a point 15 cm in front of a concavemirror.

WebIf the object is at radius, the image formed by the concave mirror is inverted, real, and of the same size as the object. Here, focus f = 15 cm. The size of its image is equal to the size of the object. So, the distance of the object must be twice of focal length (or at radius). So, image must be formed at r = 2f = 2 × 15 cm = 30 cm. can athletes drink beer
