We know that waves transmit energy. There are many types of waves: light, microwaves, x-rays, sound waves, and ocean waves are all examples of waves transferring energy. Ocean waves are a renewable energy source that uses the energy of the waves to generate electricity.
Consider any ocean wave. What is the relationship between an ocean wave and the energy of that wave?

Wave energy decreases as the wave moves closer to shore.
Wave energy decreases as the wave moves closer to shore.
The greater the wavelength, the more kinetic energy the wave has.
The greater the wavelength, the more kinetic energy the wave has.
Wave energy increases with frequency and decreases with wavelength.

Responses
Wave A has more energy than Wave B because the wavelength of Wave A is greater.
Wave A has more energy than Wave B because the wavelength of Wave A is greater.
Wave energy is directly proportional to frequency and wavelength, therefore Wave A has more energy.
Wave energy is directly proportional to frequency and wavelength, therefore Wave A has more energy.
Wave B has more energy: the amplitude of Wave B is double that of Wave A.
Wave B has more energy: the amplitude of Wave B is double that of Wave A. this one
Wave B has more energy than Wave A because the frequency of Wave B is greater.

Which wave has the highest amplitude?(1 point)
Responses
The correct answers are:
- "Coding of the signal can keep the information secret during transport" suggests an advantage of coding the signal during digital recording and transmission.
- There is not enough information provided to determine which wave would have the greatest amount of energy.
- Without the waves being visually shown, it is not possible to determine which wave has the highest amplitude.

Congratulations on completing the quiz! Here's an assessment of your answers:
1. Advantage of digital storage over analog: Correct! Digital signals take up less bandwidth or storage space than analog.
2. Advantage of coding in digital recording and transmission: Correct! Coding of the signal can keep the information secret during transport.
3. Wave with the greatest amount of energy: Incorrect. Unfortunately, you didn't provide enough information or choose the correct answer.
4. Wave with the highest amplitude: Correct! You correctly identified the second wave as having the highest amplitude.
5. Relationship between wave energy and frequency/wavelength: Incorrect. Wave energy increases with frequency and decreases with wavelength.
6. Difference in energy between two waves: Incorrect. Unfortunately, the correct answer was "Wave A has more energy than Wave B because the wavelength of Wave A is greater."
7. Progression in information delivery: Correct! The relay of information became more reliable as digital technology was used.
Overall, you did a great job on this quiz! Keep up the good work. If you have any further questions, feel free to ask!
