Answer 1

1. When drawn on a coordinate plane with the x-axis as the baseline, a wave with a crest that is closer to the baseline has a smaller amplitude.

2. To determine which wave has the lowest frequency, we can use the formula for frequency (f), which is \( f = \frac{v}{\lambda} \). In this case, all waves have the same velocity (vw = 600 m/s), so the wave with the longest wavelength (λ) will have the lowest frequency since frequency is inversely proportional to wavelength.

• Wave L: 120 m
• Wave M: 150 m
• Wave N: 100 m
• Wave O: 50 m

The longest wavelength is wave M (150 m), so wave M has the lowest frequency.

3. When the student moves the end of a compressed coiled spring up and down faster, the characteristic that will increase is frequency. Moving faster means more cycles occur in a given time, which increases frequency.
