Does 220-Hertz or 440-Hertz move faster?
220 hertz is faster, because the higher the frequency, the lower the wavelength. The wavelength directly correlates to the speed so therefore the object moving at 220 hertz is significantly faster. Not quite. The question is not about moving objects but wave speeds. The formula is velocity = frequency x wavelength, but for any given wave motion through a given medium, its velocity stays constant. Therefore the wavelength is inversely proportional to frequency alone. So a 220Hz signal travels at the same speed as the 440Hz signal, in the same medium.
What two variables are needed to calculate the speed of sound?
Distance-wavelength lambda (λ) is measured in meters (m)Time- frequency is measured in Hertz (Hz)
What are the SI units for speed of light?
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
How do you convert meters to hertz?
Strictly speaking, if somebody just looked at the words in your question, the plain answer would be "You don't; these units measure different quantities."But I suspect that you're thinking about frequency and wavelength of radio stations, light, or x-rays. Maybe even sound waves, which also have frequency and wavelength. If that's what you're thinking about then the conversion is easy:(Wavelength) = (speed) divided by (frequency), and (frequency) = (speed) divided by (wavelength)Just remember that the speed and wavelength must both be in the same units to do the arithmetic.Examples:1). I'm a ham radio operator and I enjoy operating in the 10-meter amateur band. What frequency do I transmit when I do that ?The speed of light (and radio and all other electromagnetic radiation) is about 300 million meters per second.Frequency = speed / wavelength = 300,000,000 / 10 = 30,000,000 Hertz = 30 MEGA Hz2). I work with microwave radio equipment at operates at around 6 GHz (6 billion Hertz). What's the wavelength ?Wavelength = speed / frequency = 300,000,000 / 6,000,000,000 = 0.05 meters = 5 centimeters3). My sister teaches children to play the flute. When the flute plays a sustained 'A' note ... with frequency 440 Hz ... what is the wavelength of the sound in the room ?Speed of sound = roughly 1125 ft per second depending on temperature and other things.Wavelength = speed / frequency = 1125 / 440 = 2.56 feet
How are the energy and the frequency of an electromagnetic wave related?
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.
What is the wavelength of 60 hertz?
60Hz has a wavelength of 5000 meters.
If blue light has a frequency of 6.98 10 14 hertz what is the wavelength in nanometers?
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
What unit do you get when you multiply hertz by meters?
You get a speed. If the 'Hertz' is the frequency of a particular wave, and the 'meters' is the wavelength of the same wave, then their product is the speed of that wave.
What is the speed of a wave if its wavelength is 0.02meters its frequencyis 400hz?
If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).
What is the speed of a wave that has a frequency of 250 hertz and a length of 1.3 meters?
The equation to use in this case is:speed (of the wave) = wavelength x frequency If the frequency is in hertz, and the wavelength is in meters, the speed will be in meters/second.
What is the speed when wavelength equals 27 meters and frequency equals 97 hertz?
Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/s).
What is the wavelength of a wave with a speed of 30 meters per second and a frequency of 10 hertz?
Wavelength = speed/frequency = 30/10 = 3 meters
What is the speed of a wave that has a wavelength of 60. meters and a frequency oof 6.0 hertz?
The speed of any wave is the product of wavelength x frequency. In this case, because of the units chosen (meters, and hertz, which is equal to 1/second), the speed will come out in meters/second.
What is the wavelength if the speed 331 meters per second and the hertz is 20.0?
331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.
What is the wavelength of a 30 -hertz periodic wave moving at 60 meters per second?
-30
What is the frequency of a wave if the wavelength is 10 meters and period is 5 seconds?
The frequency is 1/5 = 0.2 Hertz. The wavelength is irrelevant in this question.
What units is wavelength measured in usually?
Answer - meters or derivations of meters e.g micrometers, nanometers etc
