Which sound will reach your ear first 256 Hz or 240 Hz?
You are confused between speed of sound and pitch. The speed of sound will remain constant at specific temperature and the medium. Since 256 Hz is a higher pitch, it will be shriller. Hope that helps :D
What is the spectrum of burning kerosene?
Kerosene is a heavy mixture of hydrocarbons. Burning it creates water vapour, carbon dioxide (carbon monoxide in low oxygen conditions) and soot (unburnt carbon).
What are the wavelengths of brain waves?
This is straight from Wikipedia Delta up to 4 Hz Theta 4 - 7 Hz Alpha 8 - 12 Hz Beta 12 - 30 Hz Gamma 30 - 100 + Hz {| ! ! ! ! ! ! | |}
What is the difference between cycle and hertz?
1 hertz = 1 cycle per second. A cycle is one repetition of any particular periodic event. If something moves or acts in a repetitive way, each time it repeats that repetitive motion or action it is completing a cycle. Hertz is the unit of measurement that represents the rate at which these cycles take place. For instance, if a wheel makes one complete rotation in 1 second, then it is operating at 1 Hertz (Hz). 1 cycle / 1 second = 1 Hz If a wheel makes 10 rotations in 1 second, it is operating at 10Hz. 10 cycles / 1 second = 1 Hz Likewise, if a wheel makes 10 rotations in 10 seconds, it is operating at 10Hz. 10 cycles / 10 seconds = 1 Hz.
How do you convert Hz to Watts?
You cant. Hz measures frequency, where as Watts is a measurement of power.
Why is sound low and high pitch?
Because the rate of change in the pressure in the air differs: high pitch has a rapid vibration, low pitch a slow vibration. Humans can usually hear from a low of 20 Hz (cycles per second) to 20,000 Hz. I'm so old that I do not hear much above 12,000 Hz any more.
Which is better a high Hz or a low Hz?
Low hz
Is the pitch high or low if the frequency is low?
Pitch and frequency are simply different terms for the same thing and are directly proportional. The difference is that pitch is the subjective human perception while frequency is an objectively measured quantity in units of Hz.
How does a high-pitch musical note compare with a low one in terms of frequency?
Higher notes have higher frequencies. A typical tuning fork vibrates at 440 Hertz. That's the tone of the A above middle-C on a piano. The A one octave higher is 880 Hz (2 x 440 Hz). The A one octave above that is 1760 Hz (2 x 880 Hz). The A below middle-C is 220 Hz (440 Hz ÷ 2), the next lower A is 110 Hz, and so on. The lowest note on a piano is 27½ Hz, and the highest is 4186 Hz.
The frequency of its sound wave determines its what?
The sensation of a frequencies is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
How do vocal cords make high or low sounds?
The pitch of a sound depends on its frequency. Middle C on a piano is 261.626 Hz. The A below middle C is 220 Hz. The A above middle C, which is the frequency of a common tuning fork, is 440 Hz. The next higher A is 880 Hz.
How does a sound wave for a high pitch noise differ to one of a low pitch noise?
Sound is the vibration of air molecules. The higher the pitch, the faster the vibration. The stronger the vibration, the louder the sound. Pitch is measured in Hertz (Hz). 1 Hertz means the molecule vibrates 1 time per second (back and forth), 10 Hz means 10 times per sec. etc. Humans hear sounds from 20 Hertz (very deep bass) to 20.000 Hertz (=20 kHz) (very high sizzling)
Difference between FREQUENCY 50 Hz 60 Hz?
10 Hz 10 Hz
How high or low is a sound?
Different animals can perceive sounds at different wavelengths. For example a dog whistle has a frequency which dogs can hear but is too high for humans. Furthermore, people's sensitivity to sound frequency changes with age. In general, ordinary range for humans is 20 to 20,000 Hz.
How would you classify an em wave with a frequency of 10 hz?
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.
How would you classify an EM wave with frequency of 10 7 Hz?
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.
How would you classify an EM wave with a frequency of 10-7 Hz?
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.
