Mirror formula: If an object is at a distance u from the pole of a mirror of focal length f, then image distance is v. The Mirror formula is . The derivation of mirror formula is given in the blog ‘Reflection class – XII‘. To get the information click the given button. Click here Graph: […]
Explore MoreImage formation by a concave mirror: 1. When position of object is at infinity, position of image is at principle focus (F). Image is real inverted highly diminished. 2. When position of object is in between infinity and centre of curvature (C), position of image is in between focus (F) and the centre of curvature […]

Laws of reflection: 1st Law -The incident ray, the reflected ray, and the normal, all lie on the same plane, called the plane of incidence. The incident and reflected rays are on the opposite side of the normal. 2nd Law – The angle of incident is always equal to the angle of reflection. If i […]

Speed: The distance travelled by a particle per unit time is called speed. Speed is a scalar quantity. Speed = . If s distance travelled by a particle in time t then speed of the particle is . SI unit of speed is ms-1 and the dimension is [LT -1]. Uniform speed: A particle or […]

TYPES OF MOTON: (i) Translation motion: A body has translation motion if a line joining any two points on the body remains parallel to itself throughout the motion of the body. (a) Rectilinear motion: When the translation motion takes place along a straight line then the motion is called rectilinear motion. Example – A ball […]
