A camera is supplied with two interchangeable lenses, whose focal lengths are 35.0 and 150.0 mm. A woman whose height is 1.80 m stands 7.00 m in front of the camera. What is the height (including sign) of her image on the film, as produced by a 35.0-mm and 150.0-mm lens?
According to the Lens Magnification Equation: M = hi/ho = -di/do,
<br>where h stands for height, d stands for distances, i for image and o for object.
