Will mark as brainliest if !
light passes from substance a into substance b as shown. what could these two substances be?
a. a could be water (speed of light = 225,000 km/s); b could be air (speed of light = 300,000 km/s).
b. a could be ruby (speed of light = 170,000 km/s); b could be sapphire (speed of light = 170,000 km/s).
c. a could be ruby (speed of light = 170,000 km/s); b could be diamond (speed of light = 120,000 km/s).
d. a could be diamond (speed of light = 120,000 km/s); b could be water (speed of light = 225,000 km/s).
