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 fundamental unit of energy in physics is the Joule, or Newton-meter. The speed of light in a vaccum is 3 × 108m/sec, and this speed is a product of any light wave's frequency in Hertz (the number of light waves, or cycles, per second) and the length of its individual waves...
Step 3:Determine the path difference by using the fact that for constructive interference of waves it must be an integer number of wavelengths 1{eq}\lambda {/eq}, 2{eq}\lambda {/eq}, and so on. Step 4:Use the Pythagorean Theorem to calculate any unknown distances in the problem. ...
How to Calculate the Amplitude of Constructively Interfering Waves Step 1:Verify that the waves have constructive interference. Constructive interference occurs when the waves have a phase difference of an even multiple of {eq}\pi {/eq} Destructive interference occurs when the waves have a ...
Phase angles are calculated to determine the value (in degrees) of particular sound waves that travel throughout the air, and you can calculate them easily.
Remember, the frequency equals the number of waves that pass a specific point per second, so the observer in front actually sees a higher frequency than the observer in back of the source. The scenario above describes waves formed in water, but it also applies to sound waves and light ...
How to calculate the speed of light. Speed of Light: The speed of light in a vacuum is the same for all electromagnetic waves, 3 x 10^8 m/s. This is the fastest speed possible in our universe. However, as light enters other mediums, like air or water, it changes speed and slows...
It's impractical to count the number of sound or light waves passing a point every second, but you can calculate frequency(measured in Hertz, or cycles per second) if you know two other parameters: the length of the waves and their speed of transmission. Calculating wave speed, frequency an...
Calculating the sides of a triangle helps you to determine the perimeter of a triangle even if you only have the measure of two of the angles and one of the sides. To find the sides of the triangle, you need to use the Law of Sines. A scientific calculat
