Which factor most influences the image produced by reflection of an object on a concave mirror?
The focal point. It can affect size, real/virtual, inverted/upright.
What is the center of curvature of a mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
How do you find radius of curvature if image distance is given?
There is not enough information to answer the question.
Is the radius In math?
It is the distance, from any point on a curve, to the centre of curvature at that point.
What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
Television signal cannot be received beyond a particular distance because?
curvature of earth
What is distance of North South Distance of India?
The straight-line distance is 1741.4 miles. This is the true straight line distance which accounts for the curvature of the earth, NOT the straight line drawn on a map.
What is the straight line distance from Miami to Puerto Rico?
The straight-line distance is 1,030 miles (to the coastline of Puerto Rico). This is the true straight line distance which accounts for the curvature of the earth, NOT simply a straight line drawn on a map.
What is the angular distance of the horizon below the plane of observation caused by the curvature of the earths surface called?
DIP
Where should the bulb be placed in headlights if the beam of light have to travel long distance?
center of curvature C
What factor most influences the image produced by reflection of an object in a concave?
Distance from the mirror, curvature of the mirror.
What factor influences the image produced by reflection of an object in a concave mirror?
