Does this Mean it will produce a wide range of light colors that deviate from it?Explain briefly please

Schematic representation of dispersion by a prism. The brilliance of diamond is due in part to its large dispersion and in part to its unusually large refractive index. Crystals of rutile and of strontium tio tanate, which can be produced syntheto ically, have about eight times the dis persion of diamond! When you experience the beauty of a rainbow, as in Figure 23.3Ia IE], you are seeing the combined effects of dis persion and internal reflection. The light comes from behind you and is re fracted into many small water droplets in the air. Each ray undergoes internal reflection from the back surface of the droplet and is reflected back to you (Figures 23.3Ib [El and 23.3Ic IQ). Dispersion causes different colors to be refracted preferentially at different an 1 1 n 1
