Why can you see your feet in a mirror?
The Feet in the Mirror Problem The reflection in the mirror goes only to your knees. This says that the distance from your eye to how far down you can see on your leg will always be twice the distance from the level of you eye to the level of the bottom of the mirror, no matter where you stand.
Why do you only need a mirror half your height to see yourself?
You will see that you only need a mirror length of about 1/2 your height. This is due to the principle of reflection, which states that the angle of incidence equals the angle of reflection. A light ray from your foot strikes the mirror like a ball off a wall.
What is the smallest height a mirror would have to be for you to see your toes and the top of your head if you are 6 ft tall?
The lower edge of the mirror must be at a height that is half the distance between his feet and eyes. Since the eyes are located 6 cm from the top of his head which means it is at a height of 174 cm from his feet, the lower edge of the mirror must be 87 cm from the ground.
Why can you see your face clearly when you stand in front of the mirror?
In the daytime, light reflects off your body in all directions. That’s why you can see yourself and other people can see you. Stand in front of a mirror and some of this light from your body will stream in straight lines toward it.
Do mirrors show your true size?
It does not matter how far away you stand from a mirror; your reflection will still show the same amount of your body. The size of your image in the mirror is half the size you are in real life!
What is the height of the smallest mirror in which you could see yourself at full length does it matter how far away you are?
In the diagram below, what is the shortest mirror that would allow you to see the full length of your body however far away you stand from the mirror? The answer is half the height of yourself, and we will prove that as follows!
Would you ever be able to see your whole body in a plane mirror that is half your height?
In other words, to view an image of yourself in a plane mirror, you will need an amount of mirror equal to one-half of your height. A 6-foot tall man needs 3-feet of mirror (positioned properly) in order to view his entire image.
What happens if you stare at yourself in the mirror for 10 minutes?
Reports from people who tried mirror gazing suggest that doing it for 10 minutes a day can help ease stress and increase self-compassion. You’ll need a mirror large enough to see your face.
Why do I look skinny in the mirror but fat in pictures?
The shape and focal length of the camera lens will affect how heavy you would look in the picture. Curved lenses may cause barrel distortions and make you look fatter. If you look slimmer in mirrors but fatter in pictures, you have nothing to worry about. The camera may just be adding some “extra pounds” to your look.
Why do I look skinny in some mirrors?
“Slight curvature along only one axis can make a person look fat or skinny. “To make you look thin, your image needs to be compressed horizontally or extended vertically.” Over time most mirrors bend from top to bottom and there can be a slight curvature at the edge. “This can make a person look a little fat.”
What length should a mirror see your whole body?
In order to view your full image, the minimum size of the mirror has to be half of your height. It is really that simple. The plain logic is that, in reflection, the angle of falling light on the object is equal to the angle of reflection. Hence, the image of a 6ft tall person will require a 3ft long mirror.
Where do you look in a mirror to see your feet?
In order to view his image, the man must look as low as point Y (to see his feet) and as high as point X (to see the tip of his head). The man only needs the portion of mirror extending between points X and Y in order to view his entire image.
How tall of a mirror does a 6 foot man need?
A 6-foot tall man needs 3-feet of mirror to view his whole image regardless of where he is standing. In fact, the man needs the exact same 3-feet of mirror. A common Physics lab involves using a tall plane mirror to explore the relationship between object height and the portion of mirror needed to view an image.
How tall does a man have to be to see himself in a plane mirror?
The man is twice as tall as the distance between points X and Y. In other words, to view an image of yourself in a plane mirror, you will need an amount of mirror equal to one-half of your height. A 6-foot tall man needs 3-feet of mirror (positioned properly) in order to view his entire image.
How does distance affect the amount of mirror needed to view an image?
The two ray diagrams above demonstrate that the distance that a person stands from the mirror will not affect the amount of mirror that the person needs to see their image. Indeed in the diagram, the man’s line of sight crosses the mirror at the same locations.
