How much longer must the minimum length of a plane mirror be for a 6 ft 4 in man to see his complete heat to toe image than for a 5 ft 2 in woman to do so?

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.
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 the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
What must be the minimum length of a plane mirror in order for you to be able to see a full-length image of yourself?
The minimum length of a plane mirror needed to see a full-length image of yourself is half of your total height. This is because the mirror only needs to reflect the upper half of your body, and the image in the mirror will appear to be the same size as the actual object.
How much longer must the minimum length of a plane mirror be for a 6ft4in man to see his complete head to toe image than for a 5 ft 2 in woman to do so?
The difference in height between a 6ft 4in man and a 5ft 2in woman is 14 inches (6ft 4in - 5ft 2in = 14in). To see their complete head to toe image in a plane mirror, the mirror should be at least half the difference in height away from the person. Therefore, the mirror should be at least 7 inches longer for the man (14in/2 = 7in) than for the woman.
A tall man of height 6 feet want to see his full image Then required minimum length of mirror will be?
The minimum length of the mirror needed for the tall man to see his full image would be 6 feet. This is because the mirror needs to be at least the same height as the person in order to capture their full image.
What is the minimum length of a Plano mirror necessary for a 6 foot man to completely visualize himself?
3 feet will suffice.
How does the focal length of a single concave mirror affect the formation of an image?
The focal length of a single concave mirror affects the formation of an image by determining the distance at which the image is formed. A shorter focal length results in the image being formed closer to the mirror, while a longer focal length results in the image being formed farther away.
Which type of mirror has minimum field of view for same aparchure?
Cancave mirror is the type of mirror that has minimum field of view for same aperture.
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?
The focal length of a concave mirror will decrease when the incident violet light is replaced by red light, as red light has a longer wavelength. Conversely, the focal length of a convex mirror will increase because red light is less divergent compared to violet light.
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.
A man of height 1.4m wishes to see his full image in a plane mirror placed at distance 2m what should be the minimum height of the mirror?
The minimum height of the mirror should be equal to the height of the man's eyes, which is half of his total height. Therefore, the minimum height of the mirror should be 0.7m.
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 type of mirror is use for dressings?
A full-length mirror is typically used for dressings as it provides a complete view of the outfit from head to toe, allowing individuals to assess their overall appearance and make adjustments as needed.
