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...
Calculate the velocity for a wave on a string by dividing the tension by its mass per unit length. Make sure that the units of mass in your measurement of tension are the same as the units in which you notate the mass itself. For example, if you use newtons as your unit of tension,...
Although you can calculate the velocity of the wave by multiplying its wavelength time frequency, v = fλ, you can also calculate velocity as the difference between two phases. For two different pairs ofxandt, you can write the phasesϕ1andϕ2as 2πt1/T ± 2πx1/λ + ϕ and 2π...
NASA has an online applet to show how the lift equation impacts the flight of aircraft. This is based off a lift coefficient calculator, and you can use it to set different values of velocity, angle that the airborne object takes with respect to the ground and the surface area that the o...
Learn the wavelength formula, how to calculate wavelength, how to find a wavelength from frequency, and how to find and solve for a wavelength with...
Let's break down each part of the problem and go through the steps to find the answers. (a) To find the maximum speed attained, we can use the equation v = v0 + at, where v0 is the initial velocity, a is the acceleration, and t is the time. ...
Average speed is the speed of a person over an entire interval of movement. To calculate average speed you use the change in their position divided by the change in time, s = change in d / t, where s is speed, d is distance and t is time. Answer and Explanation: Become a...
How to Calculate Energy Consumption of Appliances. Power is the rate at which a device uses energy. So for instance an air conditioning unit, shower or kitchen range/cooker uses electrical energy much faster than a light bulb. Power is normally written on a label or embossed into the plastic...
I'm creating a folder to cache images inside Documents with my iPhone App. I want to be able to keep the size of this folder down to 1MB, so I need to to check the size in bytes of my folder. I have code to calculate the size of file, but I need the size of the folder. Wh...
To determine the oscillation frequency of simple harmonic motion, we first need to determine the amplitude and the period of the wave. The formula of the frequency of oscillation is simply the reciprocal of the period of oscillation. The amplitude is the
