waves

Question	Answer
Transverse wave	a wave where the direction of the vibration is perpendicular to the direction its traveling
Longitudinal wave	a wave where the direction of the vibration is parallel to the direction it is traveling
Properties of a wave	1. Reflection 2. Refraction 3. Interference 4. Diffraction 5. Polarisation
Define- 1. Reflection 2. Refraction	1. The bouncing of waves off of an obstacle. 2. The changing of direction of a wave when it enters a region with a different speed.
Define- 3. Interference 4. Diffraction 5. Polarisation	3. When the waves from 2 separate source s meet a new wave is formed. (constructive and destructive) 4. the sideways spreading of waves around an obstacle 5. reducing the wave to travel in one direction
The Doppler Effect	The apparent change in the frequency of waves due to the motion of the source or the observer (f ')
