What is concave mirror image formation?
Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
What are the four rules of image formation by concave mirror?
Rules for Obtaining Images Formed by a Concave Mirror
- A ray coming parallel to the principal axis is reflected through the principal focus of the concave mirror.
- The ray of light passing the principal focus becomes parallel to the principal axis after being reflected from the mirror.
What are the six cases of image formation by 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 are the applications of concave mirror?
Applications of Concave Mirror
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What is concave mirror?
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
What are the properties of concave mirror?
Concave mirrors will form both real and virtual images. When the object is closer to the mirror, a virtual and magnified image is formed. When the object is further away from the mirror, a real and diminished image is formed.
What is the formula of concave mirror?
1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What is the characteristics of concave mirror?
A concave mirror has a reflective surface that is curved inward and away from the light source. Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.
What are the advantages of concave mirror?
The concave mirrors are commonly used as shaving mirrors because when we see our face in the concave mirror then an enlarged and erect image is formed which helps in smooth shaving. 2. A concave mirror is used as the reflector in search lights, head lights of motor vehicles, solar cookers, torches and in table lamps.
What are the types of concave mirror?
Difference Between Convex and Concave Mirrors:
| Concave Mirror | |
|---|---|
| What are convex and concave mirrors? | If the inner side of the spherical mirror is reflecting, it is called a concave mirror. |
| Image | Concave mirrors can form inverted and real images and also virtual and erect images. |
What are properties of concave mirror?
What are types of concave mirror?
Concave and Convex Mirror: Smooth, polished, or gleaming surfaces are called mirrors. They produce images by reflecting the light beam. Plane and spherical mirrors are the two types of mirrors….Terms Used in Spherical Image.
| 1. | Pole | It is the midpoint of a mirror. |
|---|---|---|
| 5. | Focus | It is the point on the principal axis. |
