plsss help me ra sai​

Answer 1

Answer:

8.convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point. Photo: A convex lens makes parallel light rays converge (come together) at the focal point or focus.

Answer 2

Answer:

8)The parallel incident rays pass through the convex lens and get refracted (or bend) according to the laws of refraction. ... The point F is called the principal focus of the convex lens. A convex lens is known as converging lens because it converges a parallel beam of light rays

9)2AgCl(s)+sunlight-------=2Ag(s) +Cl2(g)

11)Focal Length - The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a 'Real image' of a distant object at its focus, as shown in the figure.
