WebSep 26, 2024 · When a plane mirror is rotated through a certain angle, the reflected ray turns through twice as much and the size of the image: remains same becomes infinity is doubled is halved 7. An object is placed 20 cm in front of a plane mirror. The mirror is moved 2 cm towards the object. 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. bird that sounds like gunshotsWebThe image is formed near the mirror if the object is placed at infinity.

WebApr 10, 2024 · The nature of image formed by a convex mirror when the object distance from the mirror is less than the distance between pole and focal point (F) of the mirror would be: (a) real, inverted and diminished in size (b) real, inverted and enlarged in size (c) virtual, upright and diminished in size (d) virtual, upright and enlarged in size Answer 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.

WebMar 11, 2024 · When an object is placed between the centre of curvature and the focus (F 1) of the convex lens, the image formed after reflection will be behind the centre of curvature (C 2 ).
