In a lens the image is formed by reflection
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. WebA lens is a shaped piece of transparent glass or plastic that refracts light. When light is refracted it changes direction due to the change in density as it moves from air into glass or plastic....

WebThe image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror. When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than compared to that of the object. 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 …
WebJul 11, 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 WebUse the law of reflection to prove that the focal length of a mirror is half its radius of curvature. That is, prove that f = R / 2. Note this is true for a spherical mirror only if its diameter is small compared with its radius of curvature. 41.
WebSince the width of the reflection area in the detection image is determined by the width of the light source module and the light aperture of the lens module, by setting a slit on the incident light path of the lens module or on the surface of the lens module, the reflection area and A clearer boundary line is formed between non-reflective ... WebRay diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a lens. The use of …
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 ). The size of the image will be greater than the object. The nature of the image will be real and inverted. The image formed at – Behind centre of curvature (C 2)
