What does a ray diagram show?
A ray diagram shows how light travels, including what happens when it reaches a surface. with an arrowhead pointing in the direction that the light travels.
What is difference between erect and inverted image?
erect image is always virtual & erect image is always formed by convex and plane mirror.
Are real images always erect True or false?
Real image of an object is a true replica of the given object. Therefore, the image formed will be an inverted image. Hence, a real image is always inverted. Therefore, the statement that a real image is always erect is false.
What image is formed behind a mirror?
Can a plane mirror ever form a real image?
Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
How is the mirror identified by seeing the image?
Plane Mirrors and Reflection When you place an object in front of a mirror, you see an image of the same object in the mirror. The object is the source of the incident rays, and the image is formed by the reflected rays. An image formed by reflection may be real or virtual.
How far is the image from the mirror?
For plane mirrors, the object distance (is equal to the image distance. That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must look at a location 2 meters behind the mirror in order to view your image.
How can you tell the difference between a real and virtual image?
The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge.
How do you tell if an image is virtual or real?
(You will have no trouble remembering this if you think about it in the right way: a real image has to be where the light is, which means in front of a mirror, or behind a lens.) Virtual images are formed by diverging lenses or by placing an object inside the focal length of a converging lens.
Can we see real image with our eyes?
We can see actual objects and real images due to the rays that are emanated from them, and virtual images due to the rays that seem to emanate from them. The rays marked in brown are (few of) the ones that get into our eye’s and help us see the object/image.
What is a real and virtual object?
A real object is one in which light rays physically emanate from the object. • A real image is one in which light rays physically intersect at the image location. • A virtual object is one from which light rays appear to emanate but physically do not.
