What else can I help you with?
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.
What is the area of a circular mirror with a radius of 38 inches?
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
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
Is the focal length equal to the radius of curvature of the mirror?
yes
Does the image formed by a concave mirror changes depending on the focal length of the mirror?
Yes its like a normal mirror close up but furthur back it is upside down.
What is a focal length of a plane mirror?
Focaal length for plane mirror is 0
Will focal length of mirror change on changing the object distance?
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.
Why does the focal length of a mirror not depend on the mirror material when the focal length of a lens does depend on the lens material?
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.
What is the hidden meaning behind the brainteaser mirror?
Full Length Mirror
WHAT HAPPENS TO THE FOCAL LENGTH OF A CONCAVE MIRROR AS THE CURVATURE OF THE MIRROR IS INCREASED?
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.
How tall mirror do you need to see your body full length?
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.
What is the focal length of concave mirror of radius 20cm?
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.
Where can I find a white 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.
How do you find focal length of concave mirror?
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.
What is the relationship between the radius of curvature and focal length in a concave mirror?
In a concave mirror, the radius of curvature is twice the focal length.
How can a rough value of the focal length of a concave mirror be obtained?
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.
Does the focal length of a spherical mirror change if immersed in water?
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.
