This Physics experience takes students into a submarine where they emit sounds at different Hz, watch the wave bounce off an object and record the shifted frequency visible in the sonar view, calculate the velocity of the object, and determine if it is moving toward the submarine or away from it.

Only available through Xennial Digital included in there 13 experiences for $349 per headset, per year subscription model.
