1rst Hypothesis: we believe that High Frequency has more energy than low frequency.
Explanation: For this hypothesis, we found that our calculations were wrong and we tested this by using the electromagnetic spectrum: radio wave, microwave, radiation, infrared, visible light, ultraviolet, X-rays and gamma rays. We went outside and made a simulation by walking and each group was one of the spectrums and we looked at how many more laps one group did than the other and we found that radio waves have the lowest frequency and gamma rays have the highest.
Materials: we used human bodies, a parking lot, and rope.

Low vs. high sound waves
2nd Hypothesis: We believe that a low-frequency wave has a longer wavelength than a high-frequency wave. …show more content…
We also found this when our group created cup phones where we had 2 cups connected to a long fishing line and what they do is you talk through them from a distance and it creates sound waves by vibration and is able to amplify/project the sound to the other phone.
Lab: we used a rope and shook it to make waves and we found that a low-frequency wave has longer wavelengths than high.we also used 2 cups, 2 pieces of tape, and a fishing
