Explanation:

Lenses - form the image objective lens - gathers light from the specimen eyepiece - transmits and magnifies the image from the objective lens to your eye nosepiece - rotating mount that holds many objective lenses tube - holds the eyepiece at the proper distance from the objective lens and blocks out stray light.

A light microscope is a biology laboratory instrument or tool, that uses visible light to detect and magnify very small objects, and enlarging them. They use lenses to focus light on the specimen, magnifying it thus producing an image.

Answer 2

Microscopes are instruments that are used in science laboratories to visualize very minute objects.

Explanation:

• Microscopes are widely used in science laboratories to visualize very minute objects such as cells, microorganisms etc.
• It is meant for the study of microscopic algae, fungi and biological specimens.
• It gives a magnified contrasting image.
• They have been constructed with special components that enable them to achieve high magnification levels.
• Microscope has both structural and optical parts.
• The three structural parts of microscope are head, base and arm.
• The optical parts of microscope are eye piece, eyepiece tube, objective lenses, nose piece, the adjustment knobs, stage, aperture, microscopic illuminator, condenser, diaphragm, condenser focus knob, abbe condenser and the rack stop.
• The optical parts of the microscope are used view, magnify and produce an image from a specimen placed on a slide.
