Observations: From image 1 to image 2 the amplitude is doubled in magintude. The speed remains constant at 173.2 cm/s meaning the pulse size does not effect the speed. From image 2 to 3 the tension is increased by 1 N instead resulting in an increase of speed from 173.2 cm/s to 200 cm/s. Tension effects wave speed.

Observations:In the three images above, the goal is to observe how frequency and wavelength are related. From image 1 to 2, the frequency is decreased from 50 Hz to 20 Hz resulting in a wavelength that is much longer (from 45cm to about 80cm). From image 2 to 3 the frequency is increased to 80 hz resulting in a very short wavelength of 20 cm. Therefore a higher frequency yields a shorter wavelength and vice versa because the wave completes a full path in a shorter distance.
