We'll shift gears now, spending some time on waves. Types of waves. A wave is a disturbance that transfers energy from one place to … P Waves. P waves (pressure or primary waves) travel as a region of compression. How would this appear? Using the diagram above, make the green dots move left and right. Summer - The lower waves of summer build sand onshore and widen the beach. Zoom Winter - Higher winter waves move sand offshore and narrow the beach. Zoom Seasonal differences - Beach just north of the Scripps pier, part of the UC Natural Reserve System. The summer beach is covered with a layer of sand that is moved south by the longshore currents and onshore by low waves. Waves. Transverse Waves (). Below is a picture of a transverse wave. What is the Wavelength of a
Transverse Wave?. The wavelength of a transverse wave is the distance between two peaks or the distance between two troughs. Wavelength can be defined as "the distance the wave has traveled during one complete cycle". Wavelength is given the symbol λ. This is the Greek letter lambda, pronounced 1. Disturbing forces: We described above the one we are interested in, the force due to wind interacting with the water surface. This can be complicated, but all we say about it here is that for the wind to put energy into the waves they must be moving slightly slower than the wind. Example Problem #1 The speed of waves in a particular guitar string is 425 m/s. Determine the fundamental frequency (1st harmonic) of the string if its length is 76.5 cm. GCSE PHYSICS. Waves.

Information today comes from studies of the paths and characteristics of seismic waves from earthquake waves traveling through the Earth, as well as from laboratory experiments on surface minerals and rocks at high pressure and temperature and studies of the Earth's motions in the Solar System, its gravity and magnetic fields, and the Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have
frequencies as high as 300 gigahertz to as low as 30 hertz (). At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km. Like all other electromagnetic waves, radio waves travel at the speed of light.
