Observing waves formed by an oscillating rod
|The waves emanate from the source at an angle
prescribed by the period of oscillation in only four
At a period shorter than the Brunt-Väisälä frequency, waves do not occur.
Brunt-Väisälä frequency: 3.9 sec.
Amplitude of the rod: approx. 0.5cm
f=135mm, F4.5, 1/15 seconds, ASA400, 2mm slit used.
5mm slit used.
Speeded up 10 times.
