A converging lens can give a maximum angular magnification of 4.0 x. What is the focal length of the lens?
Answer to relevant QuestionsWhen viewing an object with a magnifying glass whose focal length is 10 cm, a student positions the lens so that there is minimum eyestrain. What is the observed magnification? A compound microscope has an objective with a focal length of 4.00 mm and an eyepiece with a magnification of 10.0x. If the objective and eyepiece are 15.0 cm apart, what is the total magnification of the microscope? A – 150 x microscope has an eyepiece whose focal length is 4.4 cm. If the distance between the lenses is 20 cm, find the focal length of the objective. A telescope has an angular magnification of – 50 x and a barrel 1.02 m long. What are the focal lengths of the objective and the eyepiece? A nearsighted person has an uncorrected far point of 200 cm. Which type of contact lenses would correct this condition, and of what focal length should it be?
