Refraction through lens

Selina ICSE Solutions for Class 10 Physics Chapter 5 Refraction through Lens Exercise 5(A) Solution 1. A lens is a transparent refracting medium bounded by two curved surfaces which are generally spherical. Solution 2. Solution 3. Convex lens: It converge the incident rays towards the principal axis. It has a real focus. Concave lens: It diverges the incident rays away from the principal axis. It has a virtual focus. Solution 4. Equiconvex lens is converging. Solution 5. Concave lens will show the divergent action on a light beam. Solution 6. As shown in the figure the convex lens has two glass prisms and one glass block. One of the glass prisms is situated above the glass block and one below the block. Solution 7. As shown in the figure the concave lens has two glass prisms and one glass block. One of the glass prisms is situated above the glass block and one below the block. Solution 8. If a parallel beam of light is incident on a ...

: Hey, this is my homepage, so I have to say something about myself. Sometimes it is hard to introduce yourself because you know yourself so well that you do not know where to start with. Let me give a try to see what kind of image you have about me through my self-description. I hope that my impression about myself and your impression about me are not so different. Here it goes. I always wanted to be a blogger. I also wanted to be a great psychologist, like William James or Sigmund Freud, who could read people’s mind. Of course, I am nowhere close to these people, yet. I am just someone who does some teaching, some research, and some writing. But my dream is still alive. This is a brief introduction of myself. If you are interested in knowing more, read my articles or take a look at my pictures. Do not expect too much, and keep your sense of humor.
