A concave mirror of focal length 18 cm forms an erect image, three times the size of the object, how far is the object from the mirror? |
|
Answer» Answer: 12 cm Step-by-step explanation: GIVEN there is a concave MIRROR. Focal length, f = -18 cm Also, it's given that, it forms an erect image, three TIMES the size of object. Therefore, it will be a virtual image. Therefore, we will get, Object distance, u = -ve Image distance, v = +ve Now, we have, Magnification, m = 3 But, we know that, m = -v/u Therefore, we will get, => -v/u = 3 => v = - 3u => v = - 3u Now, we know the mirror formula, i.e., 1/u + 1/v = 1/f Substituting the values, we get, => 1/u - 1/3u = -1/18 => 3/3u - 1/3u = -1/18 => (3-1)/3u = -1/18 => 2/3u = -1/18 => 3u/2 = -18 => 3u = -18 × 2 => 3u = -36 => u = -36/3 => u = -12 Therefore, we have, => v = -3(-12) => v = 36 Hence, the object is at a distance of 12 cm from the mirror. |
