7.4.1 The time taken for the sound wave to return to the receiver: INCREASES
Reason: Sound travels slower in air, so it takes more time to return.
Reason: Sound travels slower in air, so it takes more time to return.
7.4.2 The frequency of the sound: REMAINS THE SAME
Reason: Frequency is determined by the sound source and doesn’t change when traveling through different media.

Solución
When sound waves travel through different media, properties like speed, time taken, and frequency can be affected based on the characteristics of the medium. Here’s how traveling through AIR instead of WOOD impacts the following:
7.4.1 The time taken for the sound wave to return to the receiver.
Answer: INCREASES
Reason:
Sound travels slower in air compared to wood. In wood, the speed of sound is typically around 3300 m/s, whereas in air, it’s approximately 343 m/s at room temperature. Since the speed is lower in air, it takes more time for the sound wave to cover the same distance and return to the receiver.

7.4.2 The frequency of the sound.
Answer: REMINS THE SAME
Reason:
The frequency of a sound wave is determined by the source of the sound and remains unchanged as it passes from one medium to another. While the speed and wavelength of the sound may vary between air and wood, the frequency remains constant because it is an intrinsic property of the sound wave emitted by the source.

While the speed and wavelength of the sound may vary between air and wood, the frequency remains constant because it is an intrinsic property of the sound wave emitted by the source.
Summary:
- Time Taken: Increases because sound travels slower in air.
- Frequency: Remains the Same as it is determined by the sound source.
Problem 7.4.1 Answer:
INCREASES—because sound travels more slowly in air, it takes more time to return.
INCREASES—because sound travels more slowly in air, it takes more time to return.
Problem 7.4.2 Answer:
REMINS THE SAME—the sound’s frequency is unchanged when traveling through air instead of wood.
REMINS THE SAME—the sound’s frequency is unchanged when traveling through air instead of wood.

The time taken for the sound wave to return to the receiver would INCREASE. Reason being: Sound travels faster in denser mediums like water compared to air. Therefore, when sound waves travel through air, which is less dense, they take longer to return to the receiver due to reduced speed.
The frequency of the sound REMAINS THE SAME. Reason being: Frequency is determined by the source of the sound and does not change when it travels from one medium to another. Whether the sound travels through air or water, the frequency remains constant, although its speed and wavelength may vary.
