Based on the calculation of the image formation by the convex mirror<\/a>,<\/u> can be concluded that if the object distance (do) is smaller than the focal length (f), the properties of the image are:<\/span><\/p>\n

– Virtual means the beam of light does not pass through the image because the image is behind the convex mirror<\/span><\/p>\n

– Upright<\/span><\/p>\n

– The farther the object is from the convex mirror, the smaller the image size<\/span><\/p>\n

  1. What type of image is formed by a convex mirror?<\/strong><\/span>\n

    Convex mirrors always form a virtual, diminished, and erect image.<\/span><\/li>\n

  2. How does the position of an object influence the position of the image in a convex mirror?<\/strong><\/span>\n

    No matter where the object is located, the image formed by a convex mirror is always located between the mirror and the focus.<\/span><\/li>\n

  3. Why are the images formed by convex mirrors diminished?<\/strong><\/span>\n

    The images are diminished because the light rays diverge upon reflection. As a result, they appear to come from a point that is closer to the mirror than the actual object, causing the image to appear smaller than the object.<\/span><\/li>\n

  4. How does the magnification ‘m’ of a convex mirror relate to the image and object distances?<\/strong><\/span>\n

    The magnification of a convex mirror is given by the ratio of the image height to the object height, which also equals the ratio of image distance ‘v’ to object distance ‘u’. For a convex mirror, ‘m’ equals -v\/u.<\/span><\/li>\n

  5. What is the significance of the negative sign in the magnification formula for convex mirrors?<\/strong><\/span>\n

    The negative sign indicates that the image is virtual and erect, as images formed by convex mirrors are always virtual and erect.<\/span><\/li>\n

  6. How is the focal length ‘f’ of a convex mirror related to the radius of curvature ‘R’?<\/strong><\/span>\n

    The focal length of a convex mirror is half the radius of curvature, so ‘f’ equals R\/2. For a convex mirror, the focal length is taken as negative, signifying that the focus is virtual.<\/span><\/li>\n

  7. Is the object distance ‘u’ positive or negative for a convex mirror?<\/strong><\/span>\n

    For a convex mirror, the object distance ‘u’ is taken as negative. This convention arises from the fact that the object is always placed in front of the mirror.<\/span><\/li>\n

  8. What is the mirror equation for a convex mirror and how is it derived?<\/strong><\/span>\n

    The mirror equation is 1\/v + 1\/u = 1\/f. It is derived from the geometry of spherical mirrors, considering the relationships between object distance, image distance, and focal length.<\/span><\/li>\n

  9. What happens to the image formed by a convex mirror as the object approaches the mirror?<\/strong><\/span>\n

    As the object approaches the mirror, the image also gets closer to the mirror, but it always remains smaller than the object and stays between the pole and the focus.<\/span><\/li>\n

  10. Why are convex mirrors often used for rear-view mirrors in vehicles?<\/strong><\/span><\/li>\n<\/ol>\n

    Convex mirrors are often used as rear-view mirrors because they form a diminished image, providing a wider field of view. This allows the driver to see more of the environment behind the vehicle, enhancing safety.<\/span><\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
