摘要：

In a previous paper published in this journal (Ronzani et al 2008 Eur. J. Phys. 29 957), an estimate of the light speed in air, obtained by measuring the time of flight of a pulsed laser beam, was reported. Using the same method and apparatus, we have improved the measure of the light speed in air, by increasing the data sample, and measured the light speed in water, obtaining an estimate of the water refractive index equal to n = 1.323 (0.016), at the wavelength of 665 nm.
