Light and Darkness
Light is one of the most mysterious things to exist. It behaves like waves and particles, is made out of tiny particles with zero mass, and makes up all of the colors we see. Light stimulates sight and makes things visible. Light travels in a straight path, but bends and turns when it passes through a transparent material, like glass. When this happens, the wavelength of the light changes, but not the frequency. Instead, the direction and speed will change and the light will refract (bend or change directions). Prisms and lenses are examples of transparent materials that refract light. In this unit of LST, we focused on the L part of the name. Light is what helps us see everything around us. In fact, light was the main ingredient for our most recent project. For this Action Project, I made a pinhole camera, or “camera obscure.” A pinhole camera is a simple camera with a tiny aperture - an opening through which light travels. The simplest definition for a pinhole camera is a dark box
