In order to see full image of a person, the minimum size of the mirror should be
one half the person's height
. This is so because, in reflection, the angle of incidence is equal to angle of reflection.
Does the distance from where you stand to the mirror affect the image of yourself in the mirror?
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!
Does the distance of the image change when the distance of the object from the mirror is increased?
The diagram shows that as the object distance is decreased, the image distance is decreased and
the image size is increased
. So as an object approaches the mirror, its virtual image on the opposite side of the mirror approaches the mirror as well; and at the same time, the image is becoming larger.
Does a mirror make you look shorter?
Another physics teacher, Dr. Ken Mellendorf of Illinois, explains it like this: “
A completely flat mirror will show an image behind it of exactly the same shape and size as the actual object
. Slight curvature along only one axis can make a person look fat or skinny.
Would a taller man be able to see his full height in the same mirror?
QUESTION Would a taller man be able to see his full height in the same mirror? (Select all that apply.)
Yes, by standing far enough from the mirror
. Yes, by shifting the position of the mirror vertically in the right way Yes, by standing close enough to the mirror.
Can we see real image in concave mirror?
Only a concave mirror can be used to produce a real image
; and this only occurs if the object is located at a position of more than one focal length from the concave mirror. Plane mirrors never produce real images. … A concave mirror will only produce a virtual image if the object is located in front of the focal point.
Do things look bigger in the mirror?
Ken Mellendorf of Illinois, explains it like this: “
A completely flat mirror will show an image behind it of exactly the same shape and size as the actual object
. Slight curvature along only one axis can make a person look fat or skinny.
Do mirrors lie?
A mirror doesn't communicate, the person looking at it, is the only one who can lie depending on their way of thinking. …
No, Mirrors never lie
but it is we who tend to still manipulate the mirror image to satisfy ourselves.
What mirror makes you look taller?
Convex mirrors make the object look shorter and wider than it really is. If the mirror is bent inward, it is a
concave mirror
. This type of mirror makes the object look taller and wider than it really is.
Why do I look thinner in the mirror than in pictures?
Because of the proximity of your face to the camera,
the lens can distort certain features
, making them look larger than they are in real life. Pictures also only provide a 2-D version of ourselves.
Why should the mirror be half your height?
In order to see full image of a person, the minimum size of the mirror should be one half the person's height. This is so because,
in reflection, the angle of incidence is equal to angle of reflection
. So, to see the image of a 6 ft tall person, a 3 ft long mirror is required.
Why does a mirror only need to be half your height?
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.
How tall does my mirror need to be?
The answer at which The Physics Classroom arrives is that a full-length mirror should be
at least half the height of the viewer to completely reflect the body
. When selecting a mirror for yourself, keep in mind that this height should also include any shoes or head wear, or you won't be able to see the entire ensemble.
Can we see real image?
A real image can be viewed on a screen
, a virtual image can not. Rays from both types can enter your eye, be refracted by your eye's lens and form a real image on your retina as @CarlWitthoft points out. So it is not the case that a real image must be viewed on a screen. It can be viewed on a screen.
Are real images always inverted?
Real images are
always located behind the mirror
. Real images can be either upright or inverted. Real images can be magnified in size, reduced in size or the same size as the object. Real images can be formed by concave, convex and plane mirrors
Is concave lens?
A concave lens is a
lens that possesses at least one surface that curves inwards
. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
