Can you distinguish concave and convex mirrors without touching them? Yes, we can distinguish between concave and convex mirrors without touching them. As we know that in a concave mirror the size of the image formed is enlarged w.r.t. the real image.
WebFeb 23, 2024 · Using mirror formula 1/v + 1/u = 1/f For plane mirror f = infinity Hence, 1/v + 1/u = 0 So, v = -u It means that image is at equal distance and in opposite side of the object. This is the true condition in image formation through plane mirror. Hence spherical mirror formula holds equally to a plane mirror. GOOD LUCK!!
