Discuss the optics involved in a magnifying glass and a microscope. Indicate the momo lens optics of a magnifying glass, how it enlarges the image, and the define the image. Use a sketch of the lens optics in a microscope, how the lenses form 2 images, their location in the microscope and how they are enlarged.
Review the different types of lenses. their nomenclature and how they affect light. Use printed diagrams of a magnifying lens and a microscope. Name the important parts Show from a sketched diagram the optics of the magnifying lens. Indicate the object position and the image position. Define as an enlarged, virtual image. Use a diagram of the lens optics for a microscope. Show how 2 images are formed and their positions. Discuss early microscopes and their optics.
to determine the focal point of a concave lens using the optics bench and laser . Using prisms and colored filters demonstrate how white light is composed of frequencies of the spectral colors. Determine how different colored objects appear when specific frequencies shine on them.
Use diagrams of the human eye and label all important physical and physiological parts. Discuss how the eye refracts light to the retina. Discuss how the eye does not refract light correctly in farsighted and nearsighted conditions. Discuss how to correct the conditions.
