Schlieren Optics | Harvard Natural Sciences Lecture

What It ShowsHow It WorksSetting It UpCommentsRefraction due to inhomogeneity in air is made visible by our single-mirror schlieren optics setup. The refraction can be caused by changes in the density, temperature, or pressure of the air immediately in front of the concave mirror. With a video camera and monitor, we can see warm convection currents rising from a candle flame or, alternatively, cold air sinking from a glass of ice water. The jet of warm air from an ordinary hair dryer is made dramatically visible. The flow of gases other than air can also be visualized with this technique. For example, sulfur hexafluoride gas is six times more dense than air, and so can be visibly poured from a bottle into a glass as if it were a liquid. This video of our setup shows the pressure antinodes of an ultrasonic standing wave as bright bands: One can also demonstrate the diffraction of light around objects. By turning down most of the lights so that there is very little ambient illumination, an object placed in front of the mirror is...Get price

Refraction of Sound | Harvard Natural Sciences Lecture

Balloons filled with helium, CO2, or insulating gas act as diverging and converging lenses, respectively. What it shows: A balloon, filled with a gas different from air, will refract sound waves. A gas denser than air turns the balloon into a converging lens and a lighter gas makes it a diverging lens. An air-filled balloon has little effect.Get price
