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...
The amplitude of the resulting wave is A1+A2, where A1 is the amplitude of the first wave and A2 is the amplitude of the second wave. We will use these steps, definitions, and equations to calculate the amplitude of constructively interfering waves in the following two examples. ...
SpeedNormal Instructors Kathryn Boddie View bio How to Calculate the Intensity Level of a Sound Wave Step 1: I W/m2 Step 2: β = 10 log ( II0 ) I0=10−12W/m2 What is the Intensity Level of a Sound Wave? Intensity Level:
Since light is a wave phenomenon, you can express Planck's equation in terms of wavelength, represented by the Greek letter lambda (λ), because for any wave, the velocity of transmission is equal to its frequency times its wavelength. Since the speed of light is a constant, denoted...
In physics, the amount of matter that an object has is reflected in its mass, which largely determines its resistance to changes in motion -- or inertia. For things that rotate or spin, however, the picture becomes more complicated; instead of mass, phys
Suppose you measure the distance between a pair of ocean waves to be 25 feet. You time how long it takes for the wave to pass a pair of reference points and calculate that it's moving about 15 miles per hour. Can you calculate the wave frequency in hertz? The answer is yes, but fi...

What's more, you could calculate the velocity of the stool after you hit it with the ball, but you have no idea what its velocity was before you hit it. This is the problem revealed by Heisenberg's Uncertainty Principle. To know the velocity of a quark we must measure it, and ...
How To Be Mean: Angular Plays Fetch By Ted Neward | October 2017 Welcome back again, MEANers. In my last column, I wrote, “One of the common needs of an Angular application is to obtain or update data from locations not inside the browser—which is usually everywhere.” I then proceed...
Step 1:Identify the frequencyfof the wave and its speedv. Step 2:Calculate the wavelengthλusing the equation:λ=vf. Step 3:The minimum path difference required for destructive interference is equal to half of the wavelength:λ2. What is Destructive Interference?
