  1. Problems practice. Here is an excerpt from Galileo's report of his attempt to determine the speed of light in a vacuum. Let each of two persons take a light contained in a lantern, or other receptacle, such that by the interposition of the hand, the one can shut off or admit the light to the vision of the other.

  2. We have 10 ready-to-use problem sets on the topic of Light Waves. These problem sets focus on the use of wave principles and equations to solve physics word problems associated with light speed, frequency, wavelength, illuminance, the Doppler shift, and two-point source interference.
