Focal point of a lens
WebApr 14, 2024 · Seeing Different Focal Lengths. 35mm is considered the equivalent focal length of a wide-angle lens whereas 50mm is considered a more normal focal length. After the 50mm focal length, we move toward the telephoto lens. When comparing the 35mm vs 50mm lens you’ll look for out-of-focus areas that indicate a shallower depth of field. WebAn object is placed at the focal point of a thin diverging lens of focal length f. What is the image distance? A) f B) 2f C) 1/f D) f/2 E) at an infinite distance. D) f/2. An object is placed 6.5 cm from a thin converging lens with a focal length of 14 cm.
