Description

In the experiment P5.6.3.4 water and acrylic glass of thickness d are held into the path of the beam, and then the resulting increase of the time-of-flight Δt is measured. With the velocity of light c in air measured in the experiment P5.6.3.3, the velocity of light cM in matter can now be determined:

Finally, the refractive index n is determined according to
