Crave the Wave

In Crave The Wave, participants will demonstrate knowledge and process skills needed to solve problems and answer questions regarding all types and areas of waves and wave motion.

Topics
Regionals Topics: General Wave characteristics-Wavelength, amplitude, frequency, period.

Wave Types- Tranverse, longitudinal, surface, torsional waves.

Wave Phenomenon- Sound and Light, reflection, standing waves, constuctive and destructive interference, refraction, effect of media diffraction, Doppler effect.

Electromagnetic Waves- Electromagnetic spectrum, relationship between frequency and wavelength, energy carried (AM/FM only), standard wavelength bands, their uses and dangers.

Others are about how the electromagnetic spectrum relates to everyday life and the knowledge of mechanical and electromagnetic waves.

Some calculations are required. Such as calculation of frequency, wavelength, and speed.

Regional Topics
So the two main types are tranverse and longitudinal. Tranverse waves are kinda like hills they move up and downin 90 degree motions. Longitudinal waves are like a slinky they move forward and there are points of higher pressure then others. Surface waves are acually a combo of the two they move in circles whiles moveing in circles. Torsional waves are spinny waves. Imagine a screw drilling in thats a pretty much a torsional wave.

Sample Questions
If the frequency is 2 Hz (2 cycles per second), what is the wavelength?

If the wavelength is 2 cm, what is the frequency in Hz (cycles per second)?
