🤓 Based on our data, we think this question is relevant for Professor Mayer's class at TTU.
The velocity of the laser beam in the unknown liquid medium is:
The velocity of light in a vacuum is:
Velocity in an unknown liquid can be given as:
vL = d/t = (35.0 × 10-2)/(1.43 × 10-9) = 2.45 × 108 m/s
A helium-neon laser beam has a wavelength in air of 633 nm. It takes 1.43 ns for the light to travel through 35.0 cm of an unknown liquid.
What is the wavelength of the laser beam in the liquid?
