Why do we hear echoes?
we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.
What can you hear but not see and only speaks when it?
An echo. It is a reflection of sound waves that bounce off a surface and return to the listener's ears.
What is a simple way to estimate how far away lightning?
First, watch for lightning. The second it hits the ground, starts counting in seconds. Stop when you hear thunder. divide the seconds by 5 to get how many miles away the lightning is. For kilometers, divide the seconds by 3.
How many miles away is the lightning when you count 40 sec from when you saw the lightning until when you hard the thunder?
What I do know is it takes 5 seconds for the sound waves to travel 1 mile.So, if it's 5 seconds per mile, take 40 seconds and divide by 5 and the answer is 8 miles. That means if you count 40 seconds and hear the thunder, the flash was 8 miles away.One more thing, every second, the sound travels .2 miles.
How far is lightning when you hear thunder?
Sound travels through air at "the speed of sound." Officially, the speed of sound is 331.3 meters per second(1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second. As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.
What happens to echo after narcissus runs away from her?
echo turns into the echo we hear today.
Why do you can hear distant sound clearly?
sound is reflected when it strikes at any medium. a distant sound becomes clear if echo or reverbation takes place. an echo happens when one hears the reflection of the original sound 0.1 seconds later. and reverbation is multiple echo, which one can hear in sikandra at agra in india
Why can you hear your echo in a open space?
You can hear your echo in an open space because sound waves bounce off surfaces and reflect back to you, creating a delayed repetition of the original sound. The time it takes for the sound to travel to a surface and bounce back determines how far away the surface is from you.
What kind of echo does a bat hear from a object moving away from it?
A bat would hear a weaker and more stretched out echo if an object is moving away from it, as the sound waves would take longer to return. This could indicate to the bat that the object is further away.
Why do we hear an echo?
we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.
What does Hear Hear mean?
echo
If the storm is 8 kilometers away how many seconds will pass before you hear thunder?
A lightning strike is about 1,100 feet away if you hear the thunder one second after the lightning flash. The distance varies somewhat with temperature, air pressure, and other environmental conditions.
What kind of echo does a bat hear from an object moving away from it?
A bat would hear a Doppler-shifted echo from an object moving away from it. This means the frequency of the echo would be lower than the frequency of the sound wave emitted by the bat. The bat's brain is able to interpret this change in frequency to understand the direction and speed of the object.
Why can you hear me but not see me?
an echo
How high is something when it takes one second to hear your echo?
If the echo is off of a wall or a cliff, then it's about 170 meters (186 yards) away from you, but the echo can't tell you how high the wall or cliff is. Conversely, if the echo is off of the ceiling, then you are in a truly huge cavern. It would be highly unlikely that there would be a ceiling 170 meters high, but it is possible. More unlikely still would be a building with a ceiling that high.
If Sound travels through air at 330 meters per second how long will it take a bat's cry to reach its prey and echo back if the prey is 1 meter away?
The total distance traveled by the sound wave is 2 m. At a rate of 330 m/s, it will take 0.00606 seconds for the bat to hear the echo.
