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 … WebThe magnification, m produced by a spherical mirror can be expressed as: m = h h ′. Here, h is the height of image and h’ is the height of the object. Magnification is also equal to the …
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 WebFocus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of …
