"How to Make It Bigger" Tiny World PPT Courseware

The magnification power of a convex lens is limited. How can we make the object larger?

Make a simple microscope

Find two convex lenses with different magnifications and adjust the distance between them to observe the object until you can see it most clearly.

Then remove a convex lens and compare the differences in the objects seen twice.

Repeat it several times and see what you find?

Move up and down to adjust the distance between the two convex lenses until you find the clearest image of the object. Use a plastic tube to fix the two lenses, and a simple microscope is ready. Try it and see if the image of the object is enlarged.

tips

In the 17th century, it was discovered that combining two convex lenses significantly improved magnification capabilities. This is because one convex lens further magnifies the image formed by the other convex lens. This is the early microscope. The microscope is an amazing invention that has broadened human vision a lot.

Use a homemade microscope to observe surrounding objects. Compared with a magnifying glass, does the magnification of the image of the object increase?

Have we discovered something new? Write down our findings.

Development of the microscope

The invention of the microscope was a great leap forward in mankind's understanding of the world, bringing mankind into a brand new microscopic world.

Optical microscope

An optical microscope is an optical instrument that uses optical principles to magnify and image tiny objects that cannot be distinguished by the human eye, so that people can extract detailed structural information.

electron microscope

An electron microscope, referred to as an electron microscope, is an instrument that uses electron beams and electron lenses instead of light beams and optical lenses based on the principles of electron optics to image the fine structure of matter at very high magnification.
