WebThis is a "wave-like" behavior and is called refraction. In this way light behaves like other waves such as sound waves. The speed of the light wave also changes when it moves from medium to medium. You can see an example of refraction of light in water if you put a straw in a glass of water. You will see how the straw seems to move to the side. WebFeb 7, 2024 · For practice set up your telescope and, using the lowest power eyepiece, point the main scope at something about 100 feet (30.5 m) away like a tree (not the sun!). Center the object in your crosshairs and make sure it's clear. Switch to a higher powered eyepiece and try again. 4 Be comfortable.
