  1. Velocity of image, mirror and object Vim Vom Velocity of Image with respect to mirror Velocity of object with respect to mirror d-t o (object distance) -2 ( Focal length) -z It is valid only along the principle axis of mirror. For plane Mirror (v=u), then Vim-Vom (2-3 ) Velocity of image with respect to ground m l sec


  2. Q. Find Velocity of image with respect to ground? mlS Velocity of mirror) 6mls By using this ngth ) Vz to(Image distance)


  3. Problems linked with mirror and mechanics problem Coefficient of restitution SHM


  4. Q. If the object is moving upward (perpendicular to principle axis ) with 2m/s. Find velocity of image formed by concave mirror of focal length 20cm and object is placed 30cm in front of concave mirror 2 Magnification (m) UA LA e dt o0m V+ -60 ) x2 By using mirror formula V2 -60m


  5. Q. Object is placed 30cm in front of concave mirror of focal length 20cm. Velocity of object is 5m/s at an angle 37. Find speed of image formed 3im 21 V -60m dt Component of Velocity of image along x-axis


  6. here, (Height of Image), hi =0 & (Height of object), ho = 0 Component of velocity of image perpendicular to principle axis will be calculated by differentiating dli IS df dlt Component of velocity of image along y-axis
