## Important Topics for HC Verma Concepts of Physics Part-1 Solutions Chapter 19: Optical Instruments

The Eye

Eyes are organs that help us to see. They offer animals with vision, the capability to receive and develop visual detail, as well as allowing numerous photo response functions that are liberated of vision. Eyes discover light and translate it into electro-chemical impulses in neurons.

The Apparent Size

The apparent diameter of a celestial object is the diameter calculated by the viewer at a distinct distance from the object. The greater the apparent diameter, the smaller will be the distance between the viewer and the object. Apparent diameter is also known as angular diameter.

Simple Microscope

A simple microscope is an instrument that uses a single lens for enlargement like a magnifying glass. This microscope uses a lens to increase the size of an object by using angular magnification alone and gives an erect enlarged virtual image to the observer.

Compound Microscope

An appliance that is used to view amplified images of small objects on a glass slide is known as a compound microscope. This microscope can attain a higher level of enlargement than stereo or other low power microscopes and decrease chromatic aberration.

Telescopes

A telescope is an optical appliance that appears objects far away by amplifying them using an arrangement of curved lenses or mirrors, or different devices used to observe faraway objects by their absorption, emission, or reflection of electromagnetic radiation.

Defects of Vision

Defects of vision are divided into three types: myopia, hypermetropia, and presbyopia. All these defects can only be rectified by the use of appropriate spherical lenses.

• In myopia, a person can see nearby objects clearly but cannot see far away objects clearly. This defect of vision is also known as near-sightedness.
• In hypermetropia, a person can see far away objects clearly but cannot see nearby objects clearly. This defect of vision is also known as farsightedness.
• In presbyopia, the power of vision of the eye decreases with ageing. In this defect, people find it difficult to see nearby objects clearly and far away objects without corrective eye-glasses.
