To find the area of a circle you use the equation: A=pi*r2 So, you would find the area of the circular mirror by plugging in the numbers. Area=3.14*(38)2 Area=4534.16 in2
Focal length, positive number with a concave mirror, negative for a convex mirror.
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
yes
Yes its like a normal mirror close up but furthur back it is upside down.
Focaal length for plane mirror is 0
No, the focal length of a mirror does not change when the object distance changes. The focal length of a mirror is a fixed property of the mirror itself. Changing the object distance will affect the position and size of the image formed by the mirror, but not the focal length.
The focal length for a mirror is determined by the law of reflection from the mirror surface. This law is not governed by the material that the mirror is made by. This means that the focal length depends only on the radius and curvature. Conversely, the focal length of a lens depends on the indices of refraction of the lens meterial and the surrounding medium.
As the curvature of a concave mirror is increased, the focal length decreases. This means that the mirror will converge light rays to a focal point at a shorter distance from the mirror. The mirror will have a stronger focusing ability.
That will depend upon your focal length--how far your eye is from the mirror. At a useful focal length the mirror can only be a few inches shorter than the subject.
The focal length of a concave mirror is half of its radius of curvature. Therefore, for a concave mirror with a radius of 20 cm, the focal length would be 10 cm.
Full Length Mirror
You can find a white full length mirror at Walmart or Target. Also you might could find a while full length mirror at Marshall's and possibly The Christmas Tree Shop.
The focal length of a concave mirror can be found by using the mirror formula, which is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object and image distances from the mirror, you can calculate the focal length using this formula.
One way to estimate the focal length of a concave mirror is to use the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object distance and the corresponding image distance, you can calculate an approximate value for the focal length of the concave mirror.
No, the focal length of a spherical mirror does not change when immersed in water. The change in medium from air to water affects the refractive index and the speed of light, but it does not affect the focal length of the mirror.
Images in a concave mirror appear inverted because the light rays converge at a focal point in front of the mirror, causing the image to be flipped. This is due to the way the mirror reflects and converges the light rays, creating a real, inverted image.
