Measuring Speed of Sound
Measuring the speed of sound can be done using several methods. The following makes use of the understanding of stationary waves in pipes with one closed end. Such a pipe will have a fundamental mode...
View ArticleSingle Slit Diffraction using Fingers
This demonstration requires no material other than your own fingers. Hold your index and middle fingers close to each other, leaving a small slit between them about 1 mm in width. Look through the slit...
View ArticlePressure Variation in Stationary Sound Waves
For sound waves, we learnt that the compressions (position of maximum pressure) and rarefactions (minimum pressure) occur at the equilibrium position of the displacement of particles. This suggests...
View ArticleMicrowave Standing Waves
In the last tutorial, we were talking about the typical wavelength of different categories of electromagnetic waves. To help us remember the typical wavelength of microwaves, I suggest that we...
