What is meant by a wavefront State the direction of propagation of waves in relation to wavefronts What is transverse wave?
An imaginary line that joins all the points on the crest of a wave. The direction of propagation of a wave is perpendicular to its wavefront. A transverse wave is a wave in which particles of the medium oscillate in the direction of the propagation of the waves. Water waves and electromagnetic waves are examples of this type of waves. A longitudinal wave is a wave which the particles of the medium oscillate in the direction parallel to the direction in which the wave moves Sound waves is the example of this type of waves.
What is longitudinal wave?
Fill in the blank with the correct answer given below frequency period Hertz ( Hz) amplitude
1. The amplitude of an oscillation is the maximum displacement for one complete oscillation . 2. The period of the oscillation is the time taken to complete one oscillation.
3. The frequency of the oscillation is the number of complete oscillation made in one second. The SI unit is Hertz ( Hz) Label the graph below and fill in the blank with correct answer. Displacement – time graph
4. In the displacement – time graph as shown above, amplitude is represented by the symbol of a and period is represented by the symbol of T

Displacement – distance graph
5. In the displacement – distance graph as shown above, amplitude is represented by the symbol of a and wavelength is represented by the symbol of λ 6. Damping is occur when in an oscillating system when the system loses ( gain / loses) energy to surrounding in the form of heat ( heat / chemical ) energy. 7. The force responsible for damping is called dissipative ( equilibrium / dissipative) 8. In a simple pendulum, its natural frequency depending on its mass ).
