As the wavefront emerges frher downward.All colors of light undergo a similar change in direction, but the change istest for those wavelengths (colors) that are slowed most in the glass. Hence,et is deflected farthest downward and red the least (see Fig. 19.17).This nonuniform deflection of light composed of many wavelengths is useor analyzing the wavelengths of light coming from a source. Light from thefor example, is made of all different wavelengths. Thus, deflection of sun-through a prism produces a rainbow of all the different colors (Fig. 19.17)he other hand, a hot gas of hydrogen atoms emits light at only certainte wavelengths: red light at about 656 nm and blue light at 486 nm,m, and 410 nm. If the light given off by hydrogen atoms is passed throughism and then projected on a screen, separate lines for each discrete wave-are seen.
