Blog Post 5: Wave Interference

1. Measure the wavelength of two drops of different amplitude, leave frequency constant.

2. Measure the wavelength of two drops with different frequency, leave amplitude constant.

3. Explain your results for Question 1 and 2.

With the frequency remaining constant the speed at which the wave travels and the number of waves visible remain constant even after changing the amplitude. Thus the wavelength does not changed. When the frequency was changed the number of drops either greatly increased or greatly decreased along with the speed at which the wave traveled. As a result the wavelength differs depending on the set frequency. The conclusion that can be drawn from this is

4. A. Measure the wavelength of the two drips, in cm:

Wavelength= 1.46 cm

B. Then measure distances from each drip(red dots) to the 6 constructive interference points (yellow dots) and report these values, cm

XA=1.63 cm XB= 1.65 XC=2.6 cm XD= 3.56 XE=3.47 XF=3.57

YA=1.65 cm YB=2.64 cm YC=1.67 cm YD=3.55 cm YE=3.5 cm YF=3.5 cm

C. The information above tells us that the two waves overlap and remain constant without interfering with the other. This can be seen through the pattern of measurements recorded, the wavelengths between points remain similar to each other and suggest that the pattern of each wave continue.
