discuss formation of images on case of concave mirrow
Answers
Ans:- A concave mirror will only produce a virtual imageif the object is located in front of the focal point. ... A plane mirror will always produce an uprightimage. A concave mirror will only produce an upright image if the object is located in front of the focal point.
this lesson, we will discuss image formation in concave mirrors. However, before we delve into the topic let us quickly recall what a concave mirror is and the principles behind its working. A concave mirror is a type of spherical mirror in which, the reflecting surface is the inner curved surface of the sphere, i.e. in this type of mirrors the reflecting surface seems to be away from the incident light source. Because of their shape, the incident light is reflected inwards (converged), thus they are also called converging mirrors and they are used for focusing light.Both laws of reflection are valid at every point on the curved surface of the mirror. The normal is drawn along the radius, i.e. it is drawn by joining the centre of curvature of the mirror to the point of incidence. The convergence of the rays after reflection is because the normal to the reflecting surface differs at each point on the mirror.
There is a formation of different images in a concave mirror. It mainly depends on the distance between the object and the mirror. Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed. These real images can be projected on a screen. The focal point and the centre of curvature of the concavemirror lie in front of the mirror.
