2. Waves transfer energy Wave: A disturbance that propagates
through a material medium or space.
Mechanical wave: Needs a medium (matter).
Waves transfer energy

4. Pulse Wave: Periodic Wave: Single disturbance in a medium
Repeated disturbance in a medium

6. TRANSVERSE LONGITUDINAL
Displacement of the wave is perpendicular to
the motion of the wave.
LONGITUDINAL
Displacement of the wave is parallel to
the motion of the wave.

7. You’re in a pool with a toy that you can’t reach.
What type of wave should you use to move it to the side of the pool?

8. the maximum displacement
Amplitude
the maximum displacement
from equilibrium
Units: meters

9. The distance it takes for a wave to repeat itself
Wavelength (λ)
The distance it takes for a wave to repeat itself
Units: meters

10. T = 1/f f = 1/T Frequency (f) - the number of vibrations per second
Units: Hz
Period (T) – the time interval it takes for the wave to repeat itself
Units: seconds
T = 1/f
f = 1/T

11. result of two waves with the same wavelength, frequency, and amplitude
A standing wave is the
result of two waves with the same
wavelength, frequency, and amplitude
traveling in opposite directions
through the same medium.

13. Standing Waves Node: point of complete destruction (no amplitude)
Antinode: point of largest amplitude

14. v = l f Wave Speed (v) - speed of the wave Units: m/s
Speed of a wave depends on the medium.
Speed increases as the density of the medium increases
v = l f
