Image Formed by Concave Lens
The condition and nature of images formed by concave lens is tabulated below:
| Object Position | Image Position | Nature of Image |
|---|---|---|
| At Infinity | At the principal focus on the same side as the object | Virtual, erect and extremely diminished |
| Between infinity and pole | Appears between focus and pole | Virtual, erect and diminished |
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.
