right hand thumb rule- maxwell’s corkscrew rule

 

                     Right hand thumb rule

 

Imagine that you are holding the current carrying straight conductor in your right hand in such a way that the thumb points towards the direction of the current. And your fingers which is surroundings the straight conductor points in the directions of the field lines of the magnetic field.  This is called as right hand thumb rule.

This is also called as maxwell’s corkscrew rule.

Sign convention for spherical lenses

Image
  Sign convention for spherical lenses Sign convention of spherical lens is similar to the sign convention of the spherical mirrors.         Object is placed on the left of the lens. It means to say that light must passes through the lens from left to light. All measurements of distance are taken from the optical centre of the lens. The focal length of a convex lens is positive. And the focal length of the concave lens is negative. All distance measured above the principal axis are positive. All distance measured below the principal axis are negative. All the distance measured in the direction of incident rays are positive. All the distance measured in the direction opposite to that of the incident rays are negative.     Lens formula and magnification   Lens formula provides the relationship between object distance (u) ,   image distance (v) and the focal length (f). lens formula is applicable of both concave lens and convex lens. The image generated by th

The refractive index

                      The refractive index The refractive index:-- When a ray of light travels from one transparent medium into another medium, the change of direction takes place in a given pair of media is called as refractive index. the refractive index can be linked with the important physical quantity, the relative speed of propagation of light in different media.   It means speed of light propagates with different speeds in different media. Speed of light is faster in vacuum with speed   of 3 * 10 8   meters/second. but in the air, the speed of light is 2.98   * 10 8 meters/second. It means speed of light in air   is compared less as compared with speed of light in the vacuum. And the speed of light in glass and water is less than the speed of light in vacuum. The refractive index determine the path of light is bent or refracted, when entering any medium.                          The refractive index is expressed as the   degree of the change of direction   of the ligh

Electromagnetic induction, fleming's right hand rule

Image
                         Electromagnetic induction   When a current carrying conductor is placed in a magnetic field in such a manner that the direction of the current is perpendicular to the magnetic field , a force is experienced. This force causes the conductor to move.     Now suppose that a conductor is moving inside the magnetic field or magnetic field is changing around a fixed conductor. This was first studied by English physicist Michael Faraday. And faraday made an important discovery that how a moving magnet can be used to generate electric currents.     To illustrate , how a moving magnet can be used to generate electric currents.   Let us take a coil of wire AB with a large number of turns. And the ends of the coil is connected to the galvanometer       And take a bar magnet. And move its north pole towards the end B of the coil. Then we observed that there is a deflection in the needles of the Galvanometer. This indicates that there is a pr
