The sound emitted by bats has a wavelength of 3.0 mm. What is the sound's frequency in air?
how do i do this??
I'm pretty sure you use the equation "velocity = frequency x wavelength," where you use your wavelength and the velocity of sound in air, which is usually around 345 m/s.
To find the frequency of the sound emitted by bats, you can use the wave equation:
Speed of Sound = Wavelength x Frequency
First, you need to know the speed of sound in air, which is approximately 343 meters per second (m/s).
Convert the wavelength from millimeters (mm) to meters (m):
1 millimeter (mm) = 0.001 meters (m)
So, the wavelength in meters would be:
3.0 mm * 0.001 m/mm = 0.003 meters (m)
Now we can rearrange the equation to solve for the frequency:
Frequency = Speed of Sound / Wavelength
Substituting the values we have:
Frequency = 343 m/s / 0.003 m
Calculating this:
Frequency ≈ 114,333 Hz
Therefore, the frequency of the sound emitted by bats is approximately 114,333 Hz (Hertz) in air.
To find the frequency of the sound emitted by bats, you can use the formula:
Frequency (f) = Speed of Sound (v) / Wavelength (λ)
The speed of sound in air is approximately 343 meters per second (m/s).
First, convert the wavelength from millimeters (mm) to meters (m). Since 1 meter is equal to 1000 millimeters, divide the wavelength by 1000:
Wavelength (λ) = 3.0 mm / 1000 = 0.003 meters (m)
Now, substitute the values into the formula to find the frequency:
Frequency (f) = 343 m/s / 0.003 m
Calculate the denominator:
Frequency (f) = 343 / 0.003 = 114,333.33 Hz
Therefore, the frequency of the bat's sound in air is approximately 114,333.33 Hz.
