What is the position of the image in the mirror?
The image in a flat mirror is the same distance behind the mirror as the object is
in front of the mirror. That's why it's called a 'virtual' image. It's a pretend, made-up
image that's not real. You can clearly see that for yourself. Simply look around the
back of the mirror, and you'll see that there's no image back there. Your eyes have
fooled your brain into thinking that there is, and that's good enough for most of us.
Usually as we say the details of the image we point out their, size, position, type and nature. In case of plane mirror, size = same size of the object position = at the same distance as the object is in front of the mirror type - erect one nature - virtual image. This means could be seen but not be caught on a screen.
An virtual image is an image that is formed not by the intersection of two light beams, but it appears that these light beams intersect at some point. The optics of convex mirror doesn't allow the light beams to intersect at any position of object in relation to the mirror. Thus one can never get any real image using convex mirror
When light shines onto an object viewed in a mirror, the rays are reflected into the eye. The rays come from a position behind the mirror. The image is the sane size as the object and the same distance from the mirror. In the image, left is right and right becomes left. The angle that the light gets pointed on to the mirror is the same as the angle that gets reflected of the mirror!
A plane (flat) mirror reflects an image which is the same size and shape, and colour as the object in front of the mirror. A concave mirror can produce a magnified image. If the image is in front of the mirror it is a real image; if behind it is a virtual (non-real) image. A real image can be cast upon a white the best) surface
Is it possible to find whether a mirror is plane concave or convex from the nature of image of an object?
Yes possible. If we place an object somehow close to the mirror and observe the image. If the image is of the same size as that of the object then it is a PLANE mirror If the image is magnified and erect, then it will be a concave mirror If the image is dimisnished then the mirror is convex in nature.
Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size. Here is a description of image formation in a convex mirror: a convex mirror always produces a virtual, upright, and smaller image…
A real time illusion transmitter for transmitting three dimensional illusions of an object comprising a first parabolic mirror for producing a real image of an illuminated object, image detection means disposed in a position to receive said real image and adapted to generate video signals for transmission by cable or electromagnetic means, a second parabolic mirror located at a remote site and having associated therewith an image projector for producing an image from signals transmitted…
The way light is reflected is different in a concave mirror depending on the position and distance from the object. when light hits the concave mirror when it is near the object, the rays are scattered and it forms a virtual image, i.e it does not come on the screen. the image will be erect and higly magnified. When it is taken further from the object, the image becomes inverted and real, i.e it can…
In the plane mirror, our image will be seen as same size of us and erect. In case of concave mirror, our image will be inverted. This is because concave mirror forms real, inverted image when object is placed behind the focus of the mirror. In case of convex mirror, the size of the image will be diminished, or smaller than us and the image will be erect too. This is because the image formed…
As the object is far away then its image will be at the principal focus of the concave mirror As the object comes towards the mirror then its image would move away from the mirror with magnified image When it is at the focus then image will be at infinity so not caught on a screen but could be seen by our eyes When the object is in between focus and mirror then a virtual…
