In terms of lenses, a simple microscope only has one lens, whereas compound microscopes use multiple lenses. The single lens of a simple microscope is what sets it apart from more complicated microscopes.
In conclusion, if you’re looking for a basic and portable tool for magnifying objects, a simple microscope is the way to go. It is the simplest kind of microscope, with only one lens, and is commonly used for basic observations.
How Does a Simple Microscope Work?
A simple microscope, also known as a magnifying glass or hand lens, is a basic optical instrument that uses a single lens to produce a magnified image of an object.
The lens in a simple microscope is convex, meaning thicker in the middle and thinner at the edges. It works by bending the light that passes through it, causing the rays to converge and form a virtual image that appears larger than the object being viewed.
In other words, when you place an object under a simple microscope, the lens magnifies the object by bending the light and focusing it on your eye or camera. The greater the curvature of the lens, the greater the magnification.
Simple microscopes typically have only one lens, unlike compound microscopes that have multiple lenses. The simplicity of the design allows for easy use and portability.
To use a simple microscope, hold the lens close to your eye and move it closer or further away from the object until the image appears clear and magnified. Alternatively, you can hold the lens close to the object and adjust the distance until the image appears magnified when viewed from the other side.
In conclusion, a simple microscope works by bending light with a single convex lens to magnify an object. Its simplicity and portability make it a convenient tool for simple magnification tasks.
