Physics 173 Internet Question of the Week


The Questions

November 10 - November 14, 1997

Question #1:

Use a search engine to conduct a search on the World Wide Web for a creative/instructive illustration of one of the following physics concepts:

Resonance

Harmonics and Music

Fundamental Frequency

Standing Waves

Be certain to find a site which suitably discusses the physics of these concepts.

Once you have identified a site which meets the above description, do the following:

  1. identify the title and the URL (address) of the page.
  2. describe the search path which you took to find the site.
  3. discuss the contents of the page and the underlying physics.

 

Optional Question #1:

Return to the "Bird in a Cage" page at the Exploratorium Museum (see last week's Question of the Week). Read the Etc. section of the page and prepare an exhibit in which illustrates the principle of the fatiguing of RGB nerve cells. Mount your exhibit on poster board accompanied by a word-processed "To Do and Notice" and a "What's Going" section (written in your own words). You can use the Exploratorium's suggestions of a blue banana or red-white-blue American flag; or you can use a creative example of your own. For another extra credit point, donate the poster board exhibit to the GBS physics department for use in later years.

 

Question #2:

A guitar string has a mass of 0.00250 kg (2.50 grams) and is pulled tight with a tension force of 485 Newtons. The string is 74 cm (0.74 m) long and is played by guitarist such that it vibrates with the fundamental frequency. Determine the speed of waves in the string, the wavelength of the wave and the frequency of the fundamental. PSYW
