RUBENS TUBE APPARATUS: Standing wave flame tube

RUBENS TUBE APPARATUS: Standing wave flame tube

•  This Rubens Tube really brings a truly exciting physics experiment to life that demonstrates the standing wave action effect of acoustic sound in a tube as a primitive oscilloscope.
•  This apparatus has many names such as a 'standing wave flame in a tube', or a 'simple flame tube' or commonly known as a 'Rubens Tube', and graphically shows the relationship between sound waves and sound pressure using a flame.
•  The robust stainless steel welded construction means trouble free operation for many years.
•  The unit is shipped with full instructions and safety guidance and is the perfect companion to the Signal Generator Mini Wave IEC1817.
•  Requires a supply of bench or bottled gas.
•  Dimensions: 1000 × 80 × 50mm
•  For ideal use in a science laboratory.
•  Invented by German physicist Heinrich Rubens in 1905.
•  Weight: 1kg

(Wikipedia excerpt:..."...In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect to time, and the oscillations at different points throughout the wave are in phase. The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes. ....")
