The speed of light in a vacuum is 3 x 10\" m/s. The speed of light in water is 2.25 x 108 mIs, 75% of cm. What happens if a photon goes through a vacuum, enters into water, and then leaves the water into vacuum? a. The photon slows down to cwate, and then speeds back to cm. b. The photon continues at the same speed throughout. c. The photon slows down to cwatep The speed of light in a vacuum is 3 x 10\" m/s. The speed of light in water is 2.25 x 10" m/s, 75% of cm. What happens if an electron traveling at 95% goes through air, enters into water, and then leaves the water into vacuum? a. The electron slows down to awe" and then speeds up to 0.95 cm. b. The electron slows down to away. c. The electron slows down to 0.95 cwater. d. The electron slows down to less than cwater, but we cannot exactly know the speed from the information provided
