How would you find the focal point of a convex mirror?

Now that you know that you can find the focal point of a convex mirror by using the intersection of the two rays, you can try it out for yourself. Using the two known rays from before (the reflected line and the line from the center of the concave surface to the image of the light source), you can find the point of intersection in your home. In order to do this, place an object with a light source behind it at a known distance from the mirror. Focus the light

How to find the center of a convex mirror?

The center of a convex mirror is the point where the rays of light coming through the mirror converge. The simplest way to find the center of a convex mirror is to use a tape measure. Measure around the circumference of the mirror. Where the tape measure ends is the center of the mirror.

How to find the focal length of a convex mirror?

If you have a convex mirror, you can find out its focal length by looking at a small object, like a penny. Put the penny in front of the mirror at arm’s length. If the image of the penny is in sharp focus, the mirror has a focal length of around 20-30cm. If the images are out of focus, you need a longer or shorter focal length mirror.

How to find the focal point of a concave mirror?

The concave mirror has its own focal point. To find it, you need to put a mark on the mirror at the place where you want the image of your face to appear. Focus the image of your face to this mark. If you can see it clearly, your mark is the correct focal point. If not, move the mark to the right or left until you see the face clearly again.

How to find the focal point of a convex mirror?

Find the focal point of a convex mirror by lining up the edges of the object with the edges of the mirror. Focus on the spot where the two edges meet. If the image is blurry, move the object or the mirror until the image becomes sharp.
