A.) To increase the magnification to 4.0, shouldthe object be moved closer to the lens or farther away? closer farther away To increase the magnification to 4.0, shouldthe object be moved closer to the lens or farther away? closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away closer farther away B.) Calculate the distance through which theobject should be moved. Calculate the distance through which theobject should be moved. closer farther away

Explanation / Answer

f = 36 cm, m = 3.1, m' = 4.0 a) object distance = p, image distance = q m = -q/p 1/p + 1/q = 1/f so m = -f/(p - f), or p = f (1 - 1/m) if m increases, p also increases a) farther away b) distance = p' - p = f(1 - 1/m') - f(1 - 1/m) = f(1/m - 1/m') =2.61 cm
