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. 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. 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. 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. Mechanical waves
• Mechanical waves- waves that requires a
medium
• Characteristic- displacement ,amplitude, wave
length.
• ocean waves, seismic waves, and sound waves

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. The eltrmagnetic spetrum
• What is the eltromagnetic spectrum

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. What does each have on the behavior
of waves
