The largest electromagnetic waves, with wavelengths from a few centimeters to over 100 meters are called radio waves. But what exactly is light In order to see, there must be light Light shines on an object, then bounces off, or reflects, back to our eyes
Our eyes are sensitive to a certain kind of light called visible light Visible light is all the colors (red, yellow, blue, etc.) that we can see But there are many other kinds…
