A hair dresser stand with nose 20cm in front of a plane mirror for what distance must she focus her eyes in order to see her nose in the mirror?
The hairdresser's eyes must be focused on a point that is 40 cm away from the mirror surface in order to see her nose image in the mirror. This is because the distance from her eyes to the mirror is 20 cm, and the distance from the mirror to the virtual image of her nose is also 20 cm, totaling 40 cm.

What is position of focus point in convex mirror and concave mirror?
In a convex mirror, the focus point is located behind the mirror, on the same side as the object. In a concave mirror, the focus point is located in front of the mirror, on the opposite side of the object.
Is the distance from the object to the mirror is less than the apparent from the image?
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
What are the properties of images that a concave mirror can produce?
there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced.
The law of reflection is all that is needed to establish the image location for an image formed by a?
plane mirror. The image location will be the same distance behind the mirror as the object's distance in front of the mirror.
How many inches a mirror should be hung above a dresser?
A mirror should typically be hung about 5 to 10 inches above a dresser. This height allows for comfortable viewing while also creating a balanced look with the dresser. The specific height can vary based on the size of the mirror and the dresser, as well as personal preference. It's important to ensure that the mirror is at eye level when standing in front of the dresser.
When you view your in a plane mirror how far behind mirror is your image compared with your distance in front of the mirror?
same distance
What is position of focus point in convex mirror and concave mirror?
In a convex mirror, the focus point is located behind the mirror, on the same side as the object. In a concave mirror, the focus point is located in front of the mirror, on the opposite side of the object.
If an object 5 millimeters high is located 15 millimeters in front of a plane mirror How far from the mirror is the image located?
The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.
Is the distance from the object to the mirror is less than the apparent from the image?
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
Where is the focus located?
The focus is the point at which light rays converge after passing through a lens or reflecting off a mirror. For a concave mirror or converging lens, the focus is in front of the mirror/lens. For a convex mirror or diverging lens, the focus is behind the mirror/lens.
What is the object image distance relationship for a flat mirror?
when dealing with a flat mirror object-distance and image-distance should be equal.
What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.

With a plane mirror what would be the relationship between di the image distance and do the object distance?
In a plane mirror, the image distance (di) is equal to the object distance (do). The image formed is virtual, upright, and the same size as the object, and it appears behind the mirror at the same distance as the object in front of the mirror.
