What is the size of the smallest vertical plane mirror in which a 6 ft tall person standing erect can see her length image?
The size of the mirror needs to be at least half the height of the person standing in front of it in order for the person to see their full length image. Therefore, a 3 ft tall vertical plane mirror would be the smallest size in which a 6 ft tall person can see their full length image.

What is the least possible vertical length of a mirror?
The least possible vertical length of a mirror would be equal to the height of a single atom. Mirror surfaces can be made at atomic scales, with heights on the order of nanometers (10^-9 meters) or even smaller.
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.
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.
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.
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 least possible vertical length of a mirror?
The least possible vertical length of a mirror would be equal to the height of a single atom. Mirror surfaces can be made at atomic scales, with heights on the order of nanometers (10^-9 meters) or even smaller.
Estimate the focal length of a typical magnifying mirror that you might purchase from a drugstore?
Reflect the sun's light with the mirror onto some kind of target. Find the distance where the dot of light is smallest. That distance is the focal length.
How can you use presentable in a sentence?
Standing in front of a full-length mirror will also help to keep you reasonably presentable.
If a man is standing more than one focal length away from the focal point of a concave mirror how will his image form in the mirror?
If a man is standing more than one focal length away from the focal point of a concave mirror, his image will form on the same side as the object, inverted and reduced in size. The image will be real, meaning it can be projected onto a screen. As he moves further away, the image will become smaller, and when he is at twice the focal length, the image size will be equal to his actual size.
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.
If a student stand 2m behind a plane mirror how far is the image?
Since the mirror reflects the image in front of it, the apparent distance of oneself standing in the mirror will be twice as far as the distance from you to the mirror. If you are standing 2 meters from the mirror, the image will appear as 4 meters away.
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 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.
What is the hidden meaning behind the brainteaser mirror?
