"Ward's Phenomena"

A Classic Demonstration!

Show relationships between frequency, length, tension and mass

Reliable and User Friendly

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

Airtight chamber reveals how sound disappears without air.

Closely wound steel helix for studying wave behavior.

Sturdy stroboscope ideal for studying periodic motion.

This self-contained apparatus explores wave velocity.

Unit consists of a sturdy metal frame carrying a DC motor with an eccentric shaft for exciting the vibrations. Clamp the frame to a table, attach a string and then simply use masses and a pulley to put tension on the string.

Aluminum tuning forks for physics experiments.
