What is amplitude?
- a
2. Maximum displacement from rest position.
What is a wave?
A means of transfer of energy through vibrations.
What is wavelength?
Distance between 2 successive troughs or crests.
What is frequency and what is its unit?
- Number of complete waves generated per second.
2. Hertz
What is a period?
Time taken to generate one complete wave.
What is speed?
- Distance moved by a wave in one second.
2. Speed of wave equals frequency times wavelength.
What is a wavefront?
Line that joins all peaks of a wave.
What is the type of waves traveling along a string?
Transverse waves.
What are transverse waves?
Waves that travel in direction perpendicular to direction of vibrations.
What are some examples of transverse waves?
Electromagnetic waves, water waves and light waves.
What are longitudinal waves?
Waves which travel in direction parallel to direction of vibrations.
What is an example of a longitudinal wave?
Sound wave.
What happens when a drop of water reaches the surface of a pool of water?
- Circular wavefront produced(line that joins all peaks of a wave).
- Circular shape of wave shows that water waves travel at constant in all directions.
- As wavefront travels outwards, energy transferred along direction of wave motion without transfer of matter.
