WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative … Web11 apr. 2024 · A positive value of magnification signifies a virtual image whereas, a negative value signifies a real image. Magnification of value greater than 1 signifies enlarged image whereas, magnification of value less than 1 signifies diminished image. CALCULATION: Given data, Magnification, M = +2 Height of the object, h o = 10cm

Magnification for Spherical Mirror Definition, Examples, Diagrams

Some optical instruments provide visual aid by magnifying small or distant subjects. • A magnifying glass, which uses a positive (convex) lens to make things look bigger by allowing the user to hold them closer to their eye. • A telescope, which uses its large objective lens or primary mirror to create an image of a distant object and then allows the user to examine the image closely with a smaller eyepiece lens, thus making the object look larger. WebThe positive sign indicates that the image is erect, virtual, and diminished. Question 6. Rohit placed a pencil perpendicular to principal axis in front of a converging mirror of focal length 30 cm. The image formed is twice the size of the pencil.

If magnification is more than 1, the image is magnified and if it is less than one image is diminished. If magnification is positive, the image is erect, virtual and if it is negative, the image is inverted, real. WebWhich of the following statements is FALSE about spherical mirrors? O the lateral magnification (M) is positive when the image is upright and negative when the image is inverted, the image location is negative whenever It forms on the same side of the mirror as the object is (p) (and thus where the light rays originate from) the same mirror equation … boarding pass online
