Optics and Optical Illusions (Science Experiments)
How do our eyes perceive light?
Optical Illusions: Can the eye be fooled?
Do you ever wonder how your eyes allow you to see? The science of light waves and how we see them is called opticsThe study of the nature of light and its properties.. To understand optics, you must first understand a little about light itself.
Visible light is a series of . These waves make up a small part of the electromagnetic spectrumThe complete array of electromagnetic radiation, including radio waves (at the longest-wavelength end), microwaves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays (at the shortest-wavelength end)., which includes many kinds of energy waves. You may be familiar with some of these, such as radio waves, microwaves, and X rays. Visible light is made of waves that are about 0.000014 to 0.000027 inches (360 to 700 nanometers) long. A is one-billionth of a meter. In this range are all the colors we can see; each color has a slightly different wavelength.
Light does all kinds of interesting things. It can...
