look at the table you completed. which wave transmits more energy per second?
Answer
Explanation:
Step1: Determine amplitude
The amplitude of a wave is the maximum displacement from the equilibrium position. From the graphs, both Wave 1 and Wave 2 have a maximum displacement of 8 cm. So the amplitude is equal for both waves.
Step2: Determine frequency
The frequency is the number of complete cycles per unit - time. Wave 2 has more cycles in the same horizontal distance (or time - interval if position is along the x - axis representing time), so the frequency is greater for Wave 2.
Step3: Determine energy per second
The energy per second of a wave is proportional to the square of the amplitude and the square of the frequency ($E\propto A^{2}f^{2}$). Since the amplitudes are equal and the frequency of Wave 2 is greater, Wave 2 transmits more energy per second.
Answer:
The amplitude is equal for both waves. The frequency is greater for Wave 2. Wave 2 transmits more energy per second.
