What is the formula of mirror equation?
The sign conventions for the given quantities in the mirror equation and magnification equations are as follows: f is + if the mirror is a concave mirror. f is – if the mirror is a convex mirror. di is + if the image is a real image and located on the object’s side of the mirror.
What is the concept of spherical mirror?
: a mirror with a surface that is either concave or convex and forms a portion of a true sphere.
What is called Mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What is convex mirror with diagram?
Ray Diagram for Convex and Concave Mirror A spherical mirror is a part of a spherical reflecting surface. Convex mirror is a curved mirror for which the reflective surface bulges out towards the light source. Convex mirrors reflect light outwards (diverging light rays) and therefore they are not used to focus light.
What is the formula of convex lens?
What is the Lens Formula for Convex Lens? Ans. According to the convex lens equation, 1/f = 1/v + 1/u. It relates the focal length of a lens with the distance of an object placed in front of it and the image formed of that object.
Why are spherical mirrors so called?
This type of mirror has its surface of reflection curved outwards against the centre. It is also known as a diverging mirror because it causes rays to diverge upon reflection. Unlike images formed by concave mirrors, an image formed by a convex mirror are virtual in nature.
What is the mirror formula for spherical mirrors?
However, as discussed above, in the small-angle approximation, the focal length of a spherical mirror is one-half the radius of curvature of the mirror, or f=R/2. Inserting this into Equation 2.3. 11 gives the mirror equation: 1do+1di=1f⏟mirror equation.
What are the applications of spherical mirror?
Spherical mirrors has various applications. Some applications of convex mirror are sunglasses, rear view mirrors, shaving mirror,etc. Some applications of concave mirrors are reflectors, converging of light, solar cooker etc.
What is V and U in mirror formula?
The distance between the object and the pole of the mirror is called the object distance(u). The distance between the image and the pole of the mirror is called Image distance(v). The distance between the Principal focus and pole of the mirror is called Focal Length(f).
WHAT IS lens formula?
What is Lens Formula? In optics, the relationship between the distance of an image (v), the distance of an object (u), and the focal length (f) of the lens is given by the formula known as Lens formula.
What is difference between mirror formula and lens formula?
What is the difference between Real and Virtual Image?Difference between Mirror and Lens.
|A mirror can be plane or spherical (concave or convex)||A lens is usually curved from either one or both surfaces.|
|Mirror formula is 1/f = 1/v + 1/u||Lena formula is 1/f = 1/v – 1/u|
What are examples of convex mirrors?
The passenger side mirror on a car, fisheye lenses, and hallway safety mirrors (used to see around corners).
What are the 3 types of mirrors?
Three common types of mirror are the plane mirror, which has a flat, or plane, surface; the convex mirror; and the concave mirror.
