Hewitt-Drew-it! PHYSICS 86. Wave Interference

Interference for waves in general, with emphasis on sound, beats, and anti-noise technology.

 

Hewitt-Drew-it! 83. Types of Waves

Transverse, longitudinal, bow, and shock waves are discussed.

 

Hewitt-Drew-it! 82. Good Vibrations and Waves

Vibrations, the waves they produce, and wave speed, are described and explained.

 

Is a quantum wavefunction a real thing?

In less than 100 seconds, Daniel Mortlock ponders whether the quantum wavefunction could be more than a mathematical function.

 

The uncertain location of electrons - George Zaidan and Charles Morton

The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus -- that particularly perplex scientists. George Zaidan and Charles Morton show how to make an educated guess of where those itty-bitty freewheeling electrons might be.

Chandra: Listening to Light

When we look up on a dark night, we see a sky filled with stars. The light from a star, like the light from a flashlight or a lightning bug, is one form of electromagnetic radiation.

Wave changer

Are your students forgetting that sound is a longitudinal wave? Maybe this is the answer.

 

Sound + Fire = Rubens' Tube

Sound waves in a tube of gas create flames of different heights that dance to the music. A metal tube with holes in it is filled with gas. The gas is lit to create a row of tiny flames. A speaker at one end plays sound into the tube, which creates a standing wave of sound: areas where air molecules are vibrating rapidly separated by areas where the air is fairly still. This produces the different heights of flames and allows the wavelength of the sound wave to be estimated.
