A convex mirror is also used as it always provides an erect and diminished image. Writing the AMBULANCE in reverse also helps the other vehicles that are a few distances from away from the ambulance to know that the ambulance is on the way behind it and therefore they also make way for the ambulance.
Which mirror is used by De?
A convex mirror is used in an ambulance. Because the image is smaller, more image can fit onto the mirror, so a convex mirror provides for a larger field of view than a plane mirror. This is why they are useful.
What is the mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What is vigilance mirror?
Vigilance mirror is made of convex mirror because convex mirror shows large field of view. Image formed in the convex mirror is small in the size and closer. So we can see clear image.
