If a hollow sphere is cut into parts and the outer surface of the cut part is silvered, then it becomes a mirror with its inner side as the reflecting surface. This type of mirror is known as a concave mirror. In a concave mirror, the reflective surface bulges away from the light source. The main purpose of a concave mirror is to have zoomed in image. The convergence effect of concave mirror is responsible for this. As a result, converging mirror is also a name for concave mirror. In this post, we have listed out the applications and uses of concave mirror in the practical world. Read on to find out more.
Uses of Concave Mirror
- Shaving mirrors
- Reflecting telescopes
- Headlights of vehicles
- Dental mirrors
- Solar furnace
Read about these in detail below.
Why Concave Mirror Have These Uses?
The concave mirror forms a virtual image of the object when it is placed near pole. Also, the image formed by the concave mirror is larger than the size of the actual object. Thus, it covers small area and magnifies it. Concave mirrors have a narrower view field than convex mirrors and plane mirrors.
Applications of Concave Mirror in Practical World
Usually military people use concave mirrors as shaving mirrors because they don’t want even tiniest hair on skin. Inverted image forms, so, is bit difficult to use.
Ophthalmoscope is an optical instrument that doctors use to check pupil of an eye. Pupil of an eye is too small to be visible to a naked eye. So, doctors need an ophthalmoscope to see it. Which in turn consists of concave mirror.
Concave mirror, due to its converging nature, collects lights coming parallel to principal axis on focus. This converging action helps to see large planets far away on a small screen nearby.
Headlights of vehicles
Engineers place bulb of headlight on focus of concave mirror. As a result, light rays move parallel to principle axis to large distance. A 12 volts bulb can throw light up to 500 meters.
Dentists use concave mirror to have a better view of cavities on teeth.
Concave mirrors are so powerful that large concave mirrors concentrate such a large amount of light that its heat content can melt metal. This is reason why solar furnace exists. It is ecofriendly because it uses light from Sun.
