WebPower P P. The power P P of a lens is defined to be the inverse of its focal length. In equation form, this is. P = 1 f. P = 1 f. where f f is the focal length of the lens, which must be given in meters (and not cm or mm). The power of a lens P P has the unit diopters (D), provided that the focal length is given in meters. WebWhen we combine several lenses or mirrors in a co-axial direction, the image formed by the lens serves as the object for the next lens or mirror, and the image formed by this setting will serve as the image for the third lens. The total magnification we get for the combination of a lens and a mirror is : M = m1*m2*m3*…….. Conclusion

WebFeb 20, 2024 · Using the law of reflection -- the angle of reflection equals the angle of incidence -- we can see that the image and object are the same distance from the mirror. This is a virtual image, since it cannot be projected -- the rays only appear to originate from a common point behind the mirror. WebReal images are formed when light rays after reflection or refraction converge at a point before a mirror or lens. While virtual images are formed when the light rays diverge after reflection or refraction. Real images appear on the screen as against virtual images never appear on the screen.

WebConvex mirror has two ray diagrams because its principal focus and the centre of curvature lies behind its reflecting surface. Therefore, not more than two positions of the object can be obtained in relation to these points unlike concave mirrors where more than two ray diagrams are constructed to find out the position of the image for different relative … WebTo work out the image distance for the image formed by the objective lens, use the lens equation, rearranged to: The magnification of the image in the objective lens is: So the height of the image is -1.8 x 1.0 = -1.8 mm.
