Resolving Power
- The resolving power of an optical instrument is defined as the capacity of the instrument to distinguish between two objects that are close together and produce distinct images of the two objects.
- In other words, resolving power changes in inverse proportion to the distance between the two objects to be resolved when viewed from an optical instrument. The images of two close-lying objects appear distinct and separate when viewed from the device.
- When a telescope is used to view two stars located close to each other; the telescope’s resolving power will depend on its capacity to resolve the images of the two stars.
- The resolving power of a lens used in a telescope can be determined by its ability to differentiate two lines or points in an object.

Diffraction of light
Diffraction is a phenomenon shown by light. When the wave of light interacts with the particle in the atmosphere it bends at the corners and scatters in the area to illuminate the whole area, this phenomenon is called the Diffraction of light. It is a property of light which is used to explain various phenomena observed in our daily life.
Let’s learn about diffraction in detail in this article.
