Hello students we have a convex mirror of radius of curvature are equals to 200 centimeters.
00:11
Let o be the optical center of the mirror and let a be the position of the object and b be the position of the image.
00:23
We are given that u that is the position of the object from the center of the mirror.
00:30
That is oa equals to 25 centimeters.
00:35
We need to find out v, that is ob, that is the distance of the image from the center of the mirror.
00:44
For that, first, we use the formula.
00:51
Focal length f is equal to half of the radius of curvature.
00:56
Let's say this is equation 1.
00:59
Thus, using this, we get focal length equals to 2 .5.
01:04
By 2 cm that equal to 100 centimeters...
