120.1. Light break and lens.

Mediumd (material)Light braking coefficient n
Vacuum1
Air1,0003
Ice1,31
Water1,33
Oil1,46
Glass1,52
Diamond2,41

Check the correct answer

Light breaking coefficient n is speed of light ratio in vacuum and in different atmosphere, where speed of light in vacuum, v is speed of light in atmosphere. Atmosphere, where light spreads slower is called an optical denser medium. In table are given light breaking coefficient in different atmospheres. In which medium light spreads with the slowest speed?
