### Waves

1. 1. wavesby:aggrey
2. 2. What is waves?• wave a disturbance that carries energy through matter or space; transfer energy without transferring matter• Substance through witch a wave travels
3. 3. Wave characteristics- wave motion• Longitudinal waves- a mechanical wave • Transverse wave- a in which the mechanical wave disturbance is in the that vibrates same direction or parallel to the perpendicular to the direction of wave direction of the motion waves motion• Earth quake p waves • ex- visible light• Ultra sounds microwave
4. 4. Wave characteristics- parts of wave• Amplitude wave-in any periodic motion the maximum distance an object moves from equilibrium.• Wave speed- the speed of a wave depends on the medium through which the wave moves.(Formula: wave speed=wave length x frequency)(v=λf)
5. 5. Wave characteristics •Frequency-the rate at• Wave length the wich the waves occur spatial period of the wave• Example-A visible light wave is 400 to 700 nanometers. Radio waves have the longest wave length
6. 6. Mechanical waves• Mechanical waves- waves that requires a medium• Characteristic- displacement ,amplitude, wave length.• ocean waves, seismic waves, and sound waves
7. 7. Electromagnetic waves• A wave of energy having a frequency within the electromagnetic spectrum• Characteristics- can travel through a medium• Examples- radio ,waves microwaves, x-rays
8. 8. The eltrmagnetic spetrum• What is the eltromagnetic spectrum
9. 9. Visible light• Roygbiv The R in ROYGBIV stands for RED, the O for ORANGE, the Y for YELLOW, the G for GREEN, the B for BLUE, the I for INDIGO and the V for VIOLET
10. 10. What does each have on the behavior of waves
