CLASS 12TH PHYSICS EXPERIMENT To find the value of v for different values of u in case of a concave mirror and to find the focal length.

To find the value of v for different values of u in case of a concave mirror and to find the focal length. Apparatus : Optical bench,concave mirror, optical needle,a meter scale. Theory: By Mirror formula , 1/f=1/v+1/u, f=uv/(u+v), where, u = distance of object from the pole of mirror v =  distance of image from the pole of mirror    f = focal length of concave mirror Ray diagram of concave mirror Procedure:  1 Take given concave mirror and turn its reflecting surface toward a distant object to obtain image on a sheet of note book. 2 Measure the distance between mirror and image formed on the sheet. This is the rough focal length of concave mirror. 3 Clamp mirror holder in one upright and fix two optical needles in two uprights on the optical bench. Place them close to each other at one end of optical bench. Adjust their heights so that tips of the needles are at the same height as the center of the mirror. Pierce a small piece of paper into the tip of the n

CBSE CLASS 10TH SCIENCE CHAPTER 12 ELECTRICITY To study concept of electricity we require the knowledge of behavior of materials and charges etc which we have studied in the lower classes. To make a true concept of chapter electricity in our mind.We will start with behavior of materials. Materials are classified for study of electricity into two categories: Conductor  Insulators. CBSE CLASS X SCIENCE CHAPTER 12 ELECTRICITY NOTES   S N Property Conductor Insulator 1 Flow of charge can flow can not flow 2 Free electrons Present in huge amount Present in less amount (negligible) 3 Charging can not be charged can be charged 4 Example copper, aluminium etc. plastic , wood, rubber etc. Electric Charge (Q or q):   Electric Charge is the physical property of a substance which cause it to exert as well as to experience a electric force when placed near some other substance. S I unit of
