2.The relation between electric displacement vector (D), Electric field (E) and Polarization (P)?
Optics
A plane mirror and a concave mirror of curvature radius 60 cm are placed facing each other, with a point object at the center of them . if the image formed by first reflection at the spherical and then at the plane mirror coincides with the object, then the separation between the two mirror will

An observer with a near point of 25cm looks through a microscope with an objective lens of focal length 1.2cm. when an object is placed 1.28cm from the objective, the angular magnification is -198 and the final image is formed at infinity a. What is the tube length of the microscope b. What is the focal length of the eyepiece
