CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The angular magnification of the eyepiece is given by the relation me=1+dfe, where me is the magnification of the eyepiece of the microscope, d is the least distance of vision and fe is the focal length of the eyepiece., where v0 is the image distance, u0 is the object distance.

Detailed explanation-2: -Thus, the values of maximum and minimum angular magnification are 6 and 5 respectively.

Detailed explanation-3: -definition. In magnification. Angular magnification is equal to the ratio of the tangents of the angles subtended by an object and its image when measured from a given point in the instrument, as with magnifiers and binoculars.

Detailed explanation-4: -When the image is formed at the near point or at the minimum distance of distinct vision, we get the maximum possible magnification. Hence, the lens should be kept 7.14 cm away in order to view the squares distinctly.
