When a light ray passes from one material (a) into another material (b) having a greater optical density, the index of refraction of (b) is ____ (less, greater) than that of (a). the wave speed ____ (increases, decreases), the wavelength in the second material is ____ than that of the first, making angle θb ____ with the normal than the angle θa; hence, the ray is bent ____ the normal. If instead the second material has a lesser optical density than the first, the index of refraction of (b) is ____ than that of (a), the wave speed ____, the wavelength in the second material is ____ than that of the first, making angle θb ____ with the normal than the angle θa; hence, the ray is bent ____ the normal.
