FAQ

Those who are looking for an answer to the question «Why can't you hear a sound when you wave your hand back and forth?» often ask the following questions:

### 👋 What is it called when sound bounces back and forth?

• Simply so, what is it called when sound bounces back? A sound that is repeated because the sound wave reflected or bounced back from a distant object. The bouncing back or change in direction of a wave after it strikes a barrier or an object. This may also be called an echo.

### 👋 Wave that moves back and forth?

A compressional wave

### 👋 In a wave particles move back and forth?

Waves that move back and forth are called longitudinal waves. An example are sound waves.

Because you can't wave it fast enough. You'd hear a sound if you could do at least 30 or 40 complete back-and-forth waves every second, and keep that up for a few seconds. That's exactly what's going on when you hear the buzz of a fly, or the whine of a mosquito. They don't wave as hard as your hand does, but they wave a lot faster. If you wave it close to your ear you can hear the sound.

We've handpicked 21 related questions for you, similar to «Why can't you hear a sound when you wave your hand back and forth?» so you can surely find the answer!

Why you hear a sound when you clap your hands together.?

the hands make a compression wave that travels through the air. Your ears pick up that compression wave and turns it into a neuron impulse that your brain registers as sound.

When a sound wave bends around a barrier so you can still hear the sound even though you cant see the source the wave has undergone what?

The sound wave has undergone refraction.

You hear a higher pitch when a sound wave has a greater?

A higher frequency.

What is the fastest seismic wave that moves back and forth?

The fastest seismic wave that also moves back and forth is the P-wave.

What kind of wave moves back and forth in the air?
• Keep in mind that it is the wave that travels; the air simply moves back and forth. This wave of molecular collisions is called a pressure wave. What Is Sound?
What is it called when a sound wave bounces back?
• A sound that is repeated because the sound wave reflected or bounced back from a distant object. The bouncing back or change in direction of a wave after it strikes a barrier or an object. This may also be called an echo. Subsequently, question is, what is a reflected sound wave called? A reflected sound waves is called an echo.
Why do you hear a sound when you clap your hands together?

the hands make a compression wave that travels through the air. Your ears pick up that compression wave and turns it into a neuron impulse that your brain registers as sound.

What kind of wave vibrates back and forth along the path the wave moves?

A longitudinal wave.

Do light waves travel back and forth?

As it turns out, there are two directions for light waves to oscillate and, consequently light is a transverse wave.

Does light oscillate back and forth between wave and particle like behavior?

No need to oscillate. It always behaves like whichever one your experiment is set up to detect.

The particles in a surface water wave move back-and-forth only?

the particles in a surface water move back- and- forth only.

What kind of wave moves back and forth in the same direction the wave travels?

Sound waves

How is the amplitude of sound wave related to hear?

amplitude is the maximum displacement of the body therefore it is related to hear

What is the lowest intensity sound wave we can hear?

I0 is chosen as the reference point because it is the lowest intensity of sound a person with normal hearing can perceive. The decibel level of a sound having an intensity of 1012 W/m2 is β = 0 dB, because log10 1 = 0. That is, the threshold of human hearing is 0 decibels.

What is the sound we hear from a shock wave?

A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound.

Where are sound wave collected to allow humans to hear?

Sound waves are collected at the outer ear.... it funnels the sounds into the ear canal

How do fish hear sound?
• Physical Hearing Adaptations Sound perception organs in fishes include cilia (nerve hairs), bladders, ossicles, otoliths, accelerometers, and mechanoreceptors in various configurations. Some fish have all of these features, some have only one. But regardless of the complexity of adaptations, all fish that we know seem to respond to sound.
How do we hear sound?

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

What happens when a sound wave enters your ear?

It collects sound waves and directs them into a narrow region which is called the ear canal. Your ear canal is a few centimeters long and ends at the eardrum.

When you hear an echo you are hearing a of the original sound wave.?

It is a reflection.

What to do when your neighbor doesn't wave back?
• If your neighbor’s behavior is exceptionally irritating but isn’t life-threatening, you may want to collect evidence and contact authorities (local precinct, cops, lawyers). Another option you have is to write a petition together with other neighbors.
