1. Wavelength The distance between one point on a wave and another point exactly like it.

2. Frequency The number of wavelengths that pass a point in one second. Measured in hertz (Hz). FM Radio station frequencies.

3. Frequency As frequency increases, wavelength becomes shorter. This is an inverse relationship.

4. Amplitude This is the “height” of a wave.

5. Amplitude The greater the amplitude, the more energy a wave has. AM Radio stations.

6. Wave Speed Another name for speed is velocity. Units for speed are usually a distance/time (cars: miles per hour)

7. Wave Speed Speed = Frequency x Wavelength Or… V = f x λ

8. Wave Speed Example: A wave has a wavelength of 2 m and a frequency of 3.5 Hz. What is the speed? V = 3.5 Hz x 2 m

9. Wave Speed Hint: 1 Hz = 1/second So V = 3.5/s x 2 m V = 7 m/s

10. Wave Speed Example: A wave has a speed of 9.0 m/s and a wavelength of 3.0 m, what is the frequency?

11. Wave Speed
