Mention any 4 points of advantages of using concave mirror than the convex mirror lenses in optical telescope.
Answers
Answer:
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed ... Such mirrors always form
Explanation:
Answer:
A concave mirror which is also called a converging mirror has its reflecting surface bulging inwards, i.e. away from the incident light. There are numerous uses of concave mirrors in daily life. It is used in the aircraft landing to guide the airplane, it is used as a torch to reflect the light rays, it is used during shaving to get an erect and enlarged image of the face, etc.
Some concave mirror uses are listed in the points below.
Shaving mirrors
Head mirrors
Ophthalmoscope
Astronomical telescopes
Headlights
Solar furnaces
Concave mirrors reflect light inward to one focal light. Therefore, they are mostly used to focus light. A concave mirror shows different image types depending on the distance between the mirror and the object. Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays. Some of the most important and common applications of the concave mirror are described below.
