Answer:

11. Light waves are electromagnetic (created by electromagnetic impulse)

12. Light waves in a medium are slower V = C / Nm where Nm is the index of refraction of the medium

13. The frequency of the vibration remains the same

14. The wavelength of light in the medium is less

λ = V / f and it was determined in 12 that the velocity is less in the medium
