WebNow if we pick a sign convention for our vectors (+ means on the left of the mirror and - mean on the right of the mirror), we can define: H_o = + h_o H_i = - h_i D_o = + d_i D_i = + d_o Now if we want to plug those vectors into the equation, we will have to do this: h_i/h_o = d_i/d_o -h_i/h_o = -d_i/d_o // multiply both sides by -1 Web2.2Concave mirror image 3Mirror shape 4Analysis Toggle Analysis subsection 4.1Mirror equation, magnification, and focal length 4.2Ray tracing 4.3Ray transfer matrix of spherical mirrors 5See also …
WebSep 10, 2024 · The spherical mirror formula is given as, Here, f is the focal length of the mirror, which is the distance from the Principal Focus and the Pole of the spherical mirror. v is the image distance of the mirror, which is the distance from the image formed and the pole of the spherical mirror. WebThe focal length of a spherical mirror is the distance of principal focus from the pole of the mirror. Thus in figure (a 1) and (b 1 ), the distance PF is the focal length of a spherical …
WebA spherical mirror has a radius of curvature R and a focal length f = R/2. The focal length f is the distance between the focus and the surface of the mirror. The figure on the right compares a parabolic and a concave spherical surface with the same focal length f. Near the symmetry axis or optical axis the curves are nearly identical. WebMirror formula for a convex mirror: Let P be the pole, F the principal focus and C the centre of curvature of a convex mirror of small aperture. Let PF = f, the focal length and PC = R, the radius of curvature of the mirror. AB is an object placed in front of the mirror perpendicular to its principal axis. A B is the virtual, erect image of the object AB formed …
