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
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.
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
Why do images in a concave mirror appear inverted?
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
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.
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 hidden meaning behind the brainteaser mirror?
Full Length Mirror
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.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
How do you derive relation between focal length and radius of curvature of convex mirror?
the curvature mirror the emage of the mirror is virtual
What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.
What is the power of a plane mirror?
Power is ZERO Since power = 1/ focal length As focal length of plane mirror is infinity, its reciprocal is 0
John has two rectangular mirrors that are similar The length of the smaller mirror is 4 inches and the width is 6 inches The width of bigger mirror is 2 feetWhat is the length of the bigger mirror?
it is 12 feet.
