Convex Mirror is a curved mirror where the reflective surface bulges out toward the light source. This bulging-out surface reflects light outwards and is not used to focus light. These mirrors form a virtual image as the focal point (F), and the centre of curvature (2F) are imaginary points in the mirror that cannot be reached. This results in ...
Convex Mirror Definition. A convex mirror is a curved mirror with the reflecting surface on the curved shape’s outer side. It has a surface that curves outward, resembling the shape of the outer surface of a sphere. Convex mirrors are also known as diverging mirrors because they cause light rays to diverge or spread out after reflection.
In the case of a convex mirror, any of the following four ray diagrams can be used for locating the image formed: a) When the ray is parallel to the principal axis, after reflection, the rays appear to diverge from the principal focus of a convex mirror. b) When a ray is directed towards the principal focus of a convex mirror, after reflecting ...
According to New Cartesian Sign Convention: (a) focal length of concave mirror is positive and that of convex mirror is negative. (b) focal length of both concave and convex mirrors is positive. (c) focal length of both concave and convex mirrors is negative. (d) focal length of concave mirror is negative and that of convex mirror is positive. Q.
It is important to know the difference between concave and convex mirror to get a clear understanding. Basically, the reflecting surface of the convex mirror bulges outside while the concave mirror bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while ...
Convex Mirror. Similarly, if the reflective surface is curved outwards, it is a convex mirror. Convex mirrors are used extensively as part of car mirrors. Depending on the focal length, the reflected image is reduced in size but the field of view is more. This is very useful for drivers as the blind spots are drastically reduced.
Procedure. Calculate the probable focal length of the convex lens by focussing the image of a distant subject (example: a tree) on a clear screen and calculating the length between the image and the lens. Fix the object needle, the mirror, and the lens on the optical bench as shown in the above figure. Then adjust their height in a way that the ...
Mirror Formula helps us to find: a. Image distance which is represented as ‘v’. b. Object distance which is represented as ‘u’. c. Focal length which is represented as ‘f’. And is written as : 1 v + 1 u = 1 f. This formula is valid for all kinds of spherical mirrors, for all positions of the object.
Convex Mirror. 1. Meaning and Other Names. Concave means rounded or hollowed like the interior of a circle or sphere. Also called a converging mirror. Convex means rounded or curved like the exterior of a circle or sphere. Also called a fish eye or diverging mirror. 2. Mirror Shape.

(a) concave mirror or convex mirror. (b) concave mirror or convex lens. (c) concave mirror or concave lens. (d) concave lens or convex lens. Q. State two uses of a convex mirror.
