- please find the answer
- why can't we write mirror formula as f = v + u
- Is magnification =f/f-u (or) f/u-f
- In which part of mirror we will take positive and negative sign?In Concave and convex mirror
- in magnification topic numerical problem solve
- a) The image formed in front of the concave mirror is real, so m is negative, m = -3, u = -10 cm As m = -v/u or -3 = -v/-10 v = -30 cm By mirror formula, 1/f = 1/v + 1/u = 1/-30 + 1/-10 = -4/30 or f = -30/4 = -7.5 cm Radius of curvature, R = 2f = 2 x (-7.5) = 15cm a) The image formed in front of the concave mirror is real, so m is negative, m = -3, u = -10 cm As m = -v/u or -3 = -v/-10 v = -30 cm By mirror formula, 1/f = 1/v + 1/u = 1/-30 + 1/-10 = -4/30 or f = -30/4 = -7.5 cm Radius of curvature, R = 2f = 2 x (-7.5) = 15cm the above answer is wrong pls check it
