Uses of Concave Mirror: A concave mirror, also called a convergence mirror, extends its reflective surface, away from incident light. Concave mirrors have many uses in daily life.
It is used in aircraft landings for landing, it is used to reflect light rays in the shape of a torch, it is used to get an embossed image of the face while shaving, etc.
Concave mirrors are mirrors that tilt inward. Used to focus light, they reflect it internally towards a focal point. Concave mirrors show different types of images, which depend on the distance between the mirror and the object. Concave mirrors are used quite often in everyday life.
1. Used in shaving mirrors
Concave mirrors are commonly used to shave due to the reflective and curved surface. The concave mirror creates an enlarged and raised image of the face when the mirror is placed close to the face.
2. Reflecting Telescopes
Concave mirrors are widely used in observational astronomy with various reflecting telescopes. In a reflection mirror, a concave mirror collects light from distant sky objects.
Since the sources of light are far away, the incoming light rays are effectively parallel. Due to the combination, the light intensity increases. The reflection of the flat mirror can then be seen through the eyepiece.
Concave mirrors are used to transmit powerful beams of light to automotive headlights. Instead of reflecting an image, they are used to focus light from a bulb. The rays of light from the bulb are reflected by the concave mirror, creating a strong ray that illuminates the street.
4. Used by Dentist
Used by Dentists to see a larger image of teeth. This is because when the teeth are placed near the teeth, the face is in concave mirror focus This creates an enhanced virtual image of the teeth so that dentists can easily see the image of the teeth.
5. Uses in the ophthalmoscope
Concave mirrors are used in optical instruments such as an ophthalmoscope. The eye has a concave mirror with a hole in the center. The doctor concentrates through small holes behind the concave mirror when a light beam is directed towards the pupil of the patient’s eye. It is visible to the retina and makes it easy for physicians to examine it.
A concave mirror is used as a condenser in a microscope. After passing the mirror, light from an external source is illuminated above the sample. Concentrate only on the light to ensure that it is relatively black around the concave mirror. The orientation of the mirror can be changed by rotation.
Large telescopes traditionally have concave mirrors at one end. A concave mirror collects light in a telescope. A concave mirror works under a microscope It works to illuminate a plane’s mirror with distant stars instead of illuminating the light up to a sample. The visitor looks at the lens on the eyebrow of the telescope and sees the reflection in the mirror.
8. Used in Solar Furnaces
Used in Solar Furnaces to Produce Heat. They have concave reflections. They focus on sunlight and reflect it. So they convert solar energy into heat energy
