WebA transverse wave on a string is given by the equation y (x,t) = A sin (kx – ωt) = 0.2 m sin (6.28 m-1x – 1.57 s-1t) Find the amplitude, time period and speed of the wave. Solution: Amplitude, A = 0.2 m Time period = 2π/ω = (2 x 3.14)/1.57 = 4 sec Speed of the wave, v = ω/k = 1.57/6.28 = 0.25 m/s 2. WebThe frequency is the number of waves that pass a point in a given period, usually expressed in Hertz (Hz). One Hz is equal to one wave passing per second. Solved Examples. For example, if we have a wavelength of 500nm (500 nanometers), we can plug that into the first equation and solve for the frequency: f = c/λ. f = 299,792,458 m/s / 500 nm
The electromagnetic wave equation is a second-order partial differential equation that describes the propagation of electromagnetic waves through a medium or in a vacuum. It is a three-dimensional form of the wave equation. The homogeneous form of the equation, written in terms of either the electric field E or the magnetic field B, takes the form: where WebJul 12, 2024 · The result is seen in Equation 1.5.2: (1.5.2) − ℏ 2 2 m d 2 ψ ( x) d x 2 + V ( x) ψ ( x) = E ψ ( x) Although this time-independent Schrödinger Equation can be useful to describe a matter wave in free space, we are most interested in waves when confined to a small region, such as an electron confined in a small region around the nucleus ...
