电磁辐射的波长范围可以从非常小到非常大。如果波长在十亿分之一米的 400 到 700 之间，我们的眼睛对它很敏感，我们称之为光。波长较小的我们看到的颜色是紫色；随着波长的增加，我们看到颜色依次变为蓝色、绿色、黄色、橙色和红色。如果波长超出这个范围，物理现象是相同的，但我们给它不同的名称，如无线电波、X射线、伽马射线等。
The wavelength of electromagnetic radiation can range from very small to very large. If the wavelength is between 400 and 700 billionths of a meter, our eyes are sensitive to it and we call it light. The smaller wavelength we see as the color violet; as the wavelength increases the we see color change to blue, green, yellow, orange and red in that order. If the wavelength is out of this range the physical phenomenon is the same but we give it different names such as radio waves, X rays, gamma rays, etc.
