To assess which statement is correct regarding the echo heard by either the bat or the porpoise, we need to consider the properties of sound travel in different mediums (air and water).
1. **Speed of Sound**: Sound travels faster in water than in air. The speed of sound in water is approximately 1500 m/s, while in air, it is about 343 m/s at room temperature.
2. **Amplitude**: The amplitude of sound waves refers to their strength or intensity, but it doesn't affect the speed of sound in different mediums.
Given this information, we can evaluate each statement:
- **Statement A**: Incorrect. This implies that sound travels faster in air, which it does not.
- **Statement B**: Correct. Although it mentions amplitude (which is not the primary factor), it correctly states that sound travels more effectively in water, allowing the porpoise to hear its echo first.
- **Statement C**: Incorrect. This again incorrectly states that sound travels faster in air.
- **Statement D**: Correct. This accurately states that sound travels faster in water, meaning the porpoise will hear its echo first.
Given the above analysis, both B and D are correct in the context that the porpoise will hear its echo first due to faster sound travel in water.
