Page 08 12. A ray of red light passes from a liquid to a transparent solid. The solid and the liquid have the same refractive index for this light. Which row in the table shows what happens to the speed and wavelength of the light as it passes from the liquid into the solid? Speed Wavelength A decreases decreases B decreases increases C no change increases D increases no change E no change no change 13. A ray of blue light passes from air into a transparent block as shown. 60º 30º 50º 40º air block The speed of this light in the block is A 1·80 × 108 m s−1 B 1·96 × 108 m s−1 C 2·00 × 108 m s−1 D 2·23 × 108 m s−1 E 2·65 × 108 m s−1.
