Mirror Formula: The relationship between the object's distance from the mirror, the image's distance from the mirror, and the mirror's focal length are stated in the mirror formula when an object is placed in front of a mirror. The followin...
It can also be expressed in terms of object distance (dₒ) and focal length (|ƒ|) for mirrors. In the case of a convex mirror, the formula m = |ƒ| / (dₒ + |ƒ|) indicates how the size of the image changes relative to the object's dist...
A camera lens has a focal length of 180.0 mm and an aperture diameter of 16.36 mm. (a) What is the ƒ-number of the lens? Verified step by step guidance 1 Identify the formula for the f-number of a lens, which is given by: f-number = focal lengt...
The focal length of a mirror is given by 1/v-1/u=2/f .If equal errors alpha are made in measuring u and v .Then relative error in View Solution The focal length of a spherical mirror is given byf=R2 , where R is radius of curvature of the mirror. For a given spherical mirror...
What is its radius of curvature?Spherical Mirror:The image formed by concave mirror is always real except when the object is placed between pole and focus. The image formed by the convex mirror is always virtual. The radius of curvature is double of magnitude...
Convex mirror: The spherical part of the mirror which is painted from the inner side is called convex mirror. The convex mirrors are the side view mirrors of cars. These types of mirrors have wider fields of view than flat mirrors, but objects appear smaller in them. These mirrors always ...
To find the radius of curvature of a convex mirror when its focal length is given, we can use the relationship between the focal length (f) and the radius of curvature (R). The formula is:

Centration is of course most critical for lenses with short focal length in the sense that a small mismatch of center position causes a strong beam deviation. Aberrations Caused by Lenses Lenses cause various types of aberrations (image degradations): Most lenses have spherical surfaces, simply bec...
