Traveling Waves - Pre-Lab This week we will be studying wave motion in general, the traveling waves through a medium, and analyze several cases of interaction with the other mediums. But first, let us define what is a wave and discuss about the two main types of traveling waves roblem 1 Fill a deep plate with water and generate a wave. Describe in our own words what a wave is. (There is no need to consult any source to look for a definition, instead try to put it in your own way of how you understand a wave.) There are two main kinds of waves depending on the direction of the particles motion and the direction of wave propagation and these are: Transverse is a wave in which the particles of the medium oscillate in a direction perpendicular to the direction of wave propagation and longitudinal is a wave where the particles oscillate in parallel to the direction of wave propagation. Problem 2: Give an example from your experience of a transverse wave, or if you had a spring, how would you generate a transverse wave?Explanation / Answer
1. The wave generated in the water in the plate is a transverse wave as the water particles in the plate vibrate perpendicular to the direction of propagation of the wave.
2. Example of a transverse wave is the wave generated in a pond if we through a stone in to the water. The water waves emerge from the point of impact of the stone in the water, which are transverse waves. Similarly if we give a spring a up and down jerks, transverse waves will be generated in the spring.
3. Example of a longitudinal wave is the sound wave propagated through air. If we tie one end of a spring to a support and give forward and backward jerks in the free end then longitudinal wave will travel down the spring in terms of consecutive compressions and relaxations.
4. Amplitude - metre, Period - second, Wavelength - metre, Frequency - second^-1 or hertz, speed of wave - metre/second.
