For 53 years, John Kapellas enjoyed the bright sky of the western US, but one day he started to burn, blister and break out in rashes whenever he was exposed to light. Now allergic to the entire spectrum of light, Kapellas has spent the...

Wave Motion demonstrates the difference between transverse and longitudinal waves in terms of motion and energy.

“Sound on the Move” explores how sound waves travel different distances depending on the type of material through which they travel.

There are three sounds ‘ed’ can make: /d/ /t/ and /id/. We use the /d/ sound if the root word ends in a vowel sound or if the root word ends in a voiced consonant sound- as in save, plan and amaze. We use the /t/ sound if the root word...

The video is a lecture presentation on experiments to find the speed of a wave on a wire. The presenter first explains the theory behind the experiment, involving the formation of a stationary wave and the measurement of wavelength to...
