u is the Object distance v is the Image distance f is the Focal Length given by f=R2 R is the radius of curvature of the spherical mirror The above formula is valid under all situations for all types ofspherical mirrors(Concave and Convex) and for all object positions. ...
The negative value for image distance indicates that the image is a virtual image located behind the mirror. Again, a negative or positive sign in front of the numerical value for a physical quantity represents information about direction. In the case of the image distance, a negative value alw...

The equation considers the effect of attitude angles on radar image positioning, reflects the imaging geometric principle of radar images in both distance and azimuth directions, removes the complicated imaging parameters, and realizes the coherence of orientation parameters of rigorous model for optical ...
For example, if the object distance and image distance are both given, then one can calculate the focal length of the lens. What is meant by thin lens? A thin lens is circular, transparent, and commonly made out of glass or plastic. It consists of two surfaces that are cut outs from ...
What is the formula for magnification? The formula for magnification is M=Hi/Ho=-Di/Do. M is the total magnification; Hi is the height of the image; Ho is the height of an object; Di is the distance from the lens to the in focus projected image; Do is the distance of the object...

It can be shown that the bending moment M of this type of cantilever is a function of the distance x measured from the fixed end of the beam, thus M = f(x). The defining equation for the function is: M=f(x)=Wx22−5WLx8+WL28 where W is the distributed load in newtons per ...
