If a magnifying glass gives an angular magnification of 1.5 x when viewed with relaxed eyes, what is the power of the lens?
Answer to relevant QuestionsA 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? The lenses used in a compound microscope have powers of + 100 D and + 50 D. If a total magnification of is desired, what should be the distance between the two lenses? An astronomical telescope has an objective and an eyepiece whose focal lengths are 60 cm and 15 cm, respectively. What are the telescope’s (a) Magnifying power and (b) Length? (a) For a given wavelength, a wider single slit will give (1) a greater, (2) a smaller, (3) the same minimum angle of resolution as a narrower slit, according to the Rayleigh criterion. (b) What are the minimum angles of ...If a camera with a 50-mm lens is to resolve two objects that are 4.0 mm from each other and both objects are 3.5 m from the camera lens, (a) What is the minimum diameter of the camera lens? (b) What is the resolving power? ...
