WebA converging lens and a spherical mirror are placed with their principal axis coinciding. Their separation equals 40 cm. A point source S is placed on the principal axis at a distance of … WebA covering lens and a spherical mirror are with their principle axis coinciding . Their separation equal 40 cm . A point source S is placed on the principal axis at a distance of 12 cm from the lens as shown in the figure . It is found that the final beam comes out parallel to the principal axis , Focal length of the lens equals 15 cm .
WebAs light rays from sun (u = ∞) converge at a point 15 cm in front of a concave mirror, hence focal length of concave mirror f = - 15 cm. To form an image of exactly same size as that … WebSep 15, 2024 · As the light rays coming from the sun are converging at a point 15 cm in front of a concave mirror, so the focal length of concave mirror is 15 cm. i.e. f = 15 cm …
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.

(d) more than 30 cm in front of the mirror. smart farm architectureWebIf 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. hillingdon planning portal
