What are the 6 cases of a concave mirror?
What are the 6 cases of a concave mirror?
There are six possibilities of the position of object in the case of concave mirror.
- Object at infinity.
- Object between infinity and centre of curvature (C)
- Object at centre of curvature (C)
- Object between centre of curvature (C) and Principal focus (F)
- Object at Principal Focus (F)
What is image formed by convex mirror?
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.
What kind of image is formed by concave mirror and concave lens?
Difference Between Convex and Concave Mirrors:
| Concave Mirror | |
|---|---|
| Image | Concave mirrors can form inverted and real images and also virtual and erect images. |
| Size | Size can be smaller, larger or of the same size depending on the position of the object. |
| Position | Depends on the position of the object. |
What kind of image is formed by concave and convex mirror?
Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror’s surface.
What image is formed by a concave lens?
virtual image
A concave lens always forms a virtual image.
What is the size of the image formed by a concave mirror when the object is at focus?
Notes: Highly enlarged image is formed by a concave mirror when the object is at focus.
How concave and convex mirrors are formed?
A concave mirror will only produce an upright image if the object is located in front of the focal point. Convex Mirror : Made by grinding a thick plane mirror into a bulging shape , using appropriate tools. Concave Mirror : made up of Acryl Plastic and is grounded into shape with the help of machines.
What is concave mirror and convex mirror?
Spherical mirrors contain curved surfaces which are painted on either one of the sides. When an inward surface of a spherical mirror is painted, then this type of mirror is considered a convex mirror. In the meantime, when the outward surface of the spherical mirror is painted, this mirror is called a concave mirror.
What is the image formed by concave lens?
Hence, the image formed by a concave lens is always erect and virtual.
How do the images formed by the concave mirror compared with the images formed by the convex lens?
For example, we show, as a later exercise, that an object placed between a concave mirror and its focal point leads to a virtual image that is upright and larger than the object. For the convex mirror, the extended image forms between the focal point and the mirror.
What type of image is formed by a concave lens?
In case of the concave lens, we always get erect images, diminished images and virtual images. Here if the object is very far away, the images formed by lenses will be all the more diminished.
How convex and concave mirrors are formed?
Convex Mirror : Made by grinding a thick plane mirror into a bulging shape , using appropriate tools. Concave Mirror : made up of Acryl Plastic and is grounded into shape with the help of machines.
