20 MHz
The frequency of a wave is given by the formula: frequency = speed / wavelength. In this case, the wavelength is 15 meters and the speed is 250 meters per second. Therefore, the frequency of the 15 meter wave traveling at 250 meters per second would be 250 / 15 = 16.67 Hz.
Wavelength is given in meters, while Hz is 1/seconds. Multiplying the two numbers gives meters/second. So 16,000 m/s.
There are many possible formulas. The simplest would be to map the hearing range directly to the visible. The speed of sound in air is about 300 meters per second and the speed of light is about 3e8 meters per second. We can hear frequencies of 20 to 20,000 Hz, and that corresponds to wavelengths of 15 down to .015 meters. We can see wavelengths from 700 nanometers down to 400 nanometers. So a straight formula would be light wave length = 20e-9 * (sound wave length) + 399.7e-9 (in meters) sound wave length = 300 / (sound frequency in Hz) (in meters) Another way would be to compress the sound into octaves and let that be a linear mapping. This would be like assigning the keys on a piano to specific colors. A formula for that might be light wave length = 100 * (Log (sound wave length)) + 582.4 (in nanometers) (and I used the same formula for sound wave length above).
There are 15,000 meter in 15 kilometers. 15 kilometers x 1000 meters/1 kilometer = 15,000 meters 1 kilometer = 1000 meters
15 micrometers = 1.5 × 10^-5 meters
The frequency of a wave is given by the formula: frequency = speed / wavelength. In this case, the wavelength is 15 meters and the speed is 250 meters per second. Therefore, the frequency of the 15 meter wave traveling at 250 meters per second would be 250 / 15 = 16.67 Hz.
The wavelength is calculated using the formula: Wavelength = Velocity / Frequency. Substituting the values given, we get Wavelength = 15 / 5.4 = 2.78 meters. Hence, the length of the wave is 2.78 meters.
Hertz and Frequency are the same thing = cycles-per-second. When used for the vibration of something .. like an electromagnetic sine-wave . . . then if that sine-wave is vibrating with a frequency between 20 Hz and 20,000 Hz, the human ear can "hear" it. If an electromagnetic wave vibrated much faster .. around 10^^15 Hz, then you'd be able to SEE it.
The frequency of a wave can be calculated using the formula: frequency = speed of light / wavelength. Given that the speed of light is approximately 3 x 10^8 m/s, the frequency of a wave with a wavelength of 3.55 x 10^-8 meters would be approximately 8.45 x 10^15 Hz.
The wavelength of a wave with a frequency of 20Hz can be calculated using the formula: wavelength = speed of light / frequency. Assuming the speed of light is approximately 3 x 10^8 m/s, the wavelength of a 20Hz wave would be 15,000,000 meters or 15 kilometers.
Wavelength = speed/frequency = 2/15 Hz = roughly 0.133... Hz.
The wavelength (λ) of a wave can be calculated using the formula ( \lambda = \frac{v}{f} ), where ( v ) is the wave speed and ( f ) is the frequency. Given a frequency of 5 Hz and a speed of 15 m/s, the wavelength is ( \lambda = \frac{15 , \text{m/s}}{5 , \text{Hz}} = 3 , \text{m} ). Therefore, the wavelength of the wave is 3 meters.
Frequency = (speed) divided by (wavelength) = (330) / (15) = 22 Hz.
To find the frequency of a wave, you can use the formula: frequency = speed of the wave / wavelength. In this case, the speed of the wave is 340 m/s and the wavelength is 15 m. Plugging these values into the formula, the frequency of the wave is 340 m/s / 15 m = 22.67 Hz.
To find the frequency, divide the number of wave crests (10) by the total time (15 seconds): Frequency = 10 wave crests / 15 seconds = 0.67 Hz or 2/3 Hz.
The frequency of a 10 wave crest in 15 seconds would be 0.67 Hz. This is calculated by dividing the number of wave crests (10) by the time taken (15 seconds).
