Images Formed by Concave Mirror
The condition and nature of image formation in concave mirror is tabulated below:
Object Position | Image Position | Nature of Image |
---|---|---|
At Infinity | The principal focus | Real, inverted and extremely diminished |
Beyond the centre of curvature | Between the centre of curvature and focus | Real, inverted and diminished |
At the centre of curvature | At the centre of curvature | Real, inverted object and image of the same size |
Between focus and centre of curvature | Beyond the centre of curvature | Real, inverted, enlarged image |
The principal focus | At Infinity | Extremely magnified |
Between the pole and principal axis | Behind the mirror | Virtual, erect and magnified |
Ray Optics – Definition, Formula, Applications
Ray Optics is the study of properties of light and optical instruments by assuming that light travels in a straight line. It is also known as geometrical optics, which deals with the geometry of light. Light always travels in a straight line, and the direction in which the light rays propagate is called the ray of light. It studies the principles and laws governing the propagation of light, particularly in the absence of wave effects such as interference and diffraction.
In this article, we will learn about ray optics, reflection, refraction, concave and convex mirrors, lenses, and formulas related to them.
