6.1 - Understanding Waves 2

Topic 6 : Waves
Sub-topic 6.1 : Understanding Waves

Learning Outcomes:
At the end of learning session, students should be able to

1. State what meant by wave front and relation with propagation of wave.
2. Define amplitude(A) , period(T), frequency(f), wavelength & wave speed(v).

Contents:

1. Wavefront: Imaginary line joining of particles of medium in the same phase and at the same distance from the source.
2. There are 2 types of wave front: (a)plane (b)circular
3. Amplitude, A - the maximum displacement from its equilibrium position.
4. Period, T - the time taken to complete an oscillation.
   
5. Frequency, f - the number of complete oscillations made by a vibrating system in one second.
   
6. Wavelength - the distance between successive points of the same phase in a wave.
7. Wave speed, v = frequency X wavelength
