Image Formed by Convex Lens
The condition and nature formed in convex lens is tabulated below:
Object Position | Image Position | Nature of Image |
---|---|---|
At Infinity | At the focal point | Real, inverted and extremely diminished |
Beyond 2F | Between F and 2F | Real, inverted and diminished |
At 2F | At 2F | Real, inverted size of the image and object is the same |
Between F and 2F | Beyond 2F | Real, inverted and bigger than the object |
At the principal focus | At infinity | Real, inverted and extremely magnified |
Between the optical centre and principal focus | Same side as the object | 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.
