Notes. 3.3.1 Progressive and stationary waves. 3.3.1.1 - Progressive Waves . A progressive wave transfers energy without transferring material and is made up of particles of a medium (or field) oscillating e.g. water waves are made of water particles moving up and down . Amplitude.
A student makes the following statements about waves. I In a transverse wave, the particles vibrate parallel to the direction of travel of the wave. II Light waves and water waves are both transverse waves.
Write an equation for the wave as a function of position and time. A wave is modeled with the function y (x, t) = (0.25 m) cos (0.30 m −1 x − 0.90 s −1 t + π 3). Find the (a) amplitude, (b) wave number, (c) angular frequency, (d) wave speed, (e) initial phase shift, (f) wavelength, and (g) period of the wave.
Define amplitude, frequency, period, wavelength, and velocity of a wave; Relate wave frequency, period, wavelength, and velocity; Solve problems involving wave properties
To find the amplitude: The y-axis of the CRO will show the displacement of the wave. The voltage/divisions setting will give the scale of the y axis. Each division will correspond to a stated voltage. Ensure the wave fills as much vertical space on the screen as possible by changing the voltage/div. .
The intensity of a wave is directly proportional to its amplitude squared, as shown below: I ntensity ∝ (amplitude) 2. 14.2 - Transverse and longitudinal waves. Transverse waves - the oscillations of particles (or fields) are at right angles to the direction of energy transfer.
Waves Summary Notes. Waves transfer energy The higher the amplitude the greater the energy of the wave. f=no. of waves produced per second T= time for 1 wave to pass a point. Transverse Wave: The particles of the medium transmitting the wave travel at right angles to the direction of energy travel. e.g. E.M. waves.
