  1. A. 1m
  2. B. 6 cm
  3. C. 4 m
  4. D. 80 cm
  5. E. 4 cm

Correct answer

6 cm

Explanation

Explanation To find the approximate distance from the lens to the image in a camera with a focal length of 6 centimeters, we can use the lens formula: 1/focal length = 1/object distance + 1/image distance Given information: - Focal length = 6 centimeters In this case, the distant scene is being photographed, so we can assume that the object's distance is very large, approaching infinity. As a result, we can approximate the lens formula as: 1/focal length ≈ 1/image distance Simplifying the equation: 1/6 cm ≈ 1/image distance Cross-multiplying: image distance ≈ 6 cm Therefore, the distance from the lens to the image is approximately 6 centimeters.
