A very simple device to convert light into sound can be made by wiring a solar cell directly to headphones (or an earpiece). The solar cell converts light into electricity and the headphones convert electricity into sound. The limitation...

Here is an introduction to the concept of waves and wavelike motion people experience anywhere and everywhere.

Resource focuses on the relationship between the frequency, wavelength and speed of light. Has a link to an interactive activity relating frequency, wavelength, and energy.

This site from Architectural Acoustics and Lighting provides a discussion of various factors affecting the acoustics of a given room. Room dimensions, the wavelength of the sound wave, the physical characteristics of the walls, the...

This lesson will discuss the differences between constructive and destructive wave interference. It is 1 of 2 in the series titled "Wave Interference."

At this site from the Nobel e-Museum, you can read about the scientific work of Lord Rayleigh (1842-1919 CE). This article includes information on his education and experiments with light and sound waves.
