I know that there is concave mirror in headlights of cars but when in the case of dippers in the headlights when we start upper dipper light diverges over a large area and when we start lower dipper light converges to a limited area.Then why it is concave mirror.
Can anyone explain phenomenon of dippers???

  ankita | Posted on : 09:20:29 AM on March 14, 2011 there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced. |
