Waves can describe sound, light or even the wavefunction of particles, but every wave has a wavenumber. This describes how it varies through space, and this depends crucially on the wavelength of the wave or its speed and frequency. For physics or chemistry students, learning to calculate a w...
Divide the wavelength into the velocity to calculate the frequency, expressed as described above as the number of cycles per second, or Hertz – written "Hz." For example, a water wave with a wavelength of 1 foot traveling at a speed of 4 inches per second has a frequency of 1/3 feet...
Calculate the mean value of a rectified sine wave given by y = | A sin 2 ? t /T | During the time period 0 < t < 1000 T . A predictor formula is used to predict the value of y at a. x b. x i c. x i + 1 d. y i ...
Surfers who want to practice aerial manoeuvrers would most likely prefer catching an onshore wind. Wind strength/speed The lower the number, the more likely a wave will be good. At speeds below five kilometres per hour (3mph), the ocean will be great regardless of whether you're going in...
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article onhow to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric ...
To calculate your speed, simply divide the distance swam by the time it took to complete that distance (Speed = distance swam/ swim time) So if, for instance, you want to find your speed per lap, it would be: Speed = length of lap/ lap time. If you want to find your total speed...
How does tension affect wave speed?Speed of a Wave:For some types of waves, such as light and sound, the speed of the wave is determined by the medium though which it travels. For other waves however, they can be affected by the tension, mass, and length of the substance through ...
One drawback of using software to calculate the duty cycle is that the processing speed in general.(c) Using Scan Interface to measure the duty cycle First, select the Scan Interface mode in your LabVIEW project or NI MAX. Second, select the digital input module ...

wavelength in ångstroms or meters is to first convert the energy to joules. You can then plug it directly into Planck's equation, and using 6.63 × 10-34m2kg/s for Planck's constant (h) and 3 × 108m/s for the speed of light (c), you can calculate the ...
