The purpose of this experiment was to explore the relationship between wavelength and frequency.
Procedure
- Two people held each end of the spring and stood 3m away from each other.
- Put a piece of tape on the spring.
- One person started pulsing one end of the spring until one wavelength was produced.
- Started timing when the tape was on its peak.
- Recorded the time that took the tape reached its peak 10 times.
- Repeated the same steps for two more trials.
- Conducted the same experiment when two people stood 4m and 5m away from the each other.

The product of wavelengh and frequency were close to each other with different wavelenghs. The relationship beteween wavelenght and frequency was λ=constant/ƒ (inverse). This constant was the propagated speed of the wave.
