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...
Here is the equation to use when calculating w/v percent for a solution: w/v%=massingofsolutevolumeinmLoftotalsolution×100%Making Solutions of a Given Concentration So then, if you were asked to make 100 mL of a 17% w/v solution of sodium azide, how would you do this? You can make...
Step 2:Calculate the wavelength {eq}\lambda {/eq} using the equation: {eq}\lambda=\frac{v}{f} {/eq}. Plug the speed and frequency of the waves into the equation and solve for wavelength: {eq}\lambda=\frac{343\frac{m}{s}}{700Hz} {/eq} ...
Let’s take a closer look at local maxima and minima, absolute maxima and minima, and how to calculate the function’s maximum and minima. Maxima and Minima Points: The place in a given interval where the values of the function near that point are always less than the value of the ...

Using Calculus to Find Acceleration Acceleration is measured as the change in velocity over change in time (ΔV/Δt), where Δ is shorthand for “change in”. For example, let’s calculateausing the example for constantaabove. The velocity at t = 10 is 10 m/s and the velocity at t ...
Now that we have the period (T) and the pulse width (PW), we can calculate the duty cycle (D) with the following equation: D=PWT As an example, if PW is 0.02 seconds and T is 0.05 seconds, then D=0.020.05=0.4\ or \40% ...
Firstly, there is no time-dependence (though that should have been implied by the name of the equation). Standing waves remain constant over time (except in phase), so the probability density of the particle remains constant. Thus, time at which the wavefunction is captured is irr...
To calculate the phase constant of a wave, use the equation 2π/λ for wavelength "lambda" λ. The wavelength is the length of a full cycle of the wave; for example, if you place a point at the top of a "peak" on a waveform and another point at an identical spot on an adjacent...
To calculate the phase shift, you need the frequency and period of the waves. For example, an electronic oscillator may produce sine waves at a frequency of 100 Hz. Dividing the frequency into 1 gives the period, or duration of each cycle, so 1/100 gives a period of 0.01 seconds. The...
