If you are looking for the answer of is how big a sound wave is, you’ve got the right page. We have approximately 10 FAQ regarding is how big a sound wave is. Read it below.
Write Yes if the statement is correct or No if
Ask: Write Yes if the statement is correct or No if it is not. Write your
answers on a separate sheet of paper.
1. The loudness of sound refers to how strong the sound seems to us
when it reaches our ears.
2. The volume of a sound depends on the strength of vibrations.
3. The sound is heard louder if we are near the source and then gradually
fades or becomes softer as we move away from it.
4. A sound wave travels at different speed through different media.
5. Sounds, like lights, also bounce back when they hit a smooth surface.
6. We can hear an echo if we are too close to a big hard wall. The sound we
make bounces back very fast and mixes with the original sound.
7. We always hear an echo even when the original sound is too weak.
8. Car blowing its horn and the seemingly endless barking of a dog are
examples of noise.
9. When the vibrations are fast, you hear a loud sound. When the vibrations
are slow, we create a soft sound.
10. Sound travels in solids, in liquids, and in gases. Sound travels the
fastest through solid, then liquid, and slowest in gas.

1 Echolocation is the use of sound waves and echoes to determine where objects
are in space. Bats use echolocation to navigate and find food in the dark. To echolocate, bata
send out sound waves from the mouth or nose. When the sound waves hit an object, they
produce cobous. The echo bounces of the object and returns to the bats’ ears. Bats listen to the
echoes to figure out where the object is, how big it is, and its shape.
Using echolocation, bats can detect objects as thin as a human hair in complete
darkness. Echolocation allows bats to find insects the size of mosquitoes, which many bats like
to eat. Bats aren’t blind, but they can use echolocation to find their way around very quickly in
total darkness

The first thing to do is marinate the pork belly overnight in soy sauce and
crushed garlic and vinegar. Drain the marinade. Save it for later. Heat a cooking pot, add
a few tablespoons of cooking oil. Add pork with garlic Cook the pork until it turns brown
The pork needs to be cooked until tender. Do this by pouring the remaining marinade, also
add water. whole peppercorn and dried bay leaves. Let the liquid boil for 40 minutes or
longer to tenderize the pork. Add salt if you think it is needed

Explanation:
1. The text explains all about Echolocation so clearly, it’s “explanation.”
2. The text shows the correct steps or procedure in cooking meat so it’s “procedure.”
