Webv = -v (Image distance is negative, since image formed by concave mirrors are generally on the left side or direction opposite to the incidence ray) Using mirror formula, 1/f = 1/v +1/u or, 1/f = (-u-v)/uv or, f = -uv/ (u+v) As you can see, The value of f is n Continue Reading 19 William DeVore Worked in electron optics for over 30 years.
