This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.
