The speed of light can be both calculated and measured. Light waves are formed by mutually interacting orthogonal electric and magnetic fields. Using properties of these electric and magnetic fields, you can arrange the equations of physics into a partial differential equation, called the "wave equation". This equation contains a constant in it, which is the wave-speed of light. It's value is found from other physical constants, and is about 3 106 km/sec. This value was measured in a vacuum and found to be within excellent agreement. James Clerk Maxwell first theoretically found the speed of light from what is now called the Maxwell equations.

Wavespeed = frequency x wavelength
The biggest limitation by far is that an exact solution is possible for only a small number of initial conditions. For example, one can figure out the solution for permitted states of one electron around a nucleus. However, there is no exact solution for even two electrons around a nucleus.
Frequency = Wave speed / Wavelength.
To show that a wave function is a solution to the time-independent Schrödinger equation for a simple harmonic oscillator, you substitute the wave function into the Schrödinger equation and simplify. This will involve applying the Hamiltonian operator to the wave function and confirming that it equals a constant times the wave function.
Biot-Savart's law describes the magnetic field generated by a steady current flowing in a wire. It states that the magnetic field at a point in space is proportional to the current flowing through the wire and inversely proportional to the distance from the wire. This equation is fundamental in calculating magnetic fields around current-carrying conductors.
Maxwell found that electromagnetic radiations travel at the speed of light by using his equations of electromagnetism, which predicted the existence of electromagnetic waves propagating at that speed. This discovery confirmed the connection between electricity, magnetism, and light, leading to the unification of these phenomena in what is now known as electromagnetic theory.
The phase angle in a wave equation can be found by comparing the equation to a standard form, such as (y = A \sin(\omega t + \phi)), where (\phi) is the phase angle. This angle represents the horizontal shift of the wave relative to a standard sine curve. You can determine the phase angle by comparing the equation to the standard form and identifying the value that corresponds to the horizontal shift in the wave.
The wave function in quantum mechanics is derived by solving the Schrödinger equation for a given physical system. The Schrödinger equation describes how the wave function evolves in time, and its solution provides information about the quantum state of the system. Different boundary conditions and potentials will lead to different wave functions.
James Maxwell developed the theory that light is an electromagnetic wave by combining the equations of electricity and magnetism, known as Maxwell's equations. He predicted that electromagnetic waves could travel through space at the speed of light and demonstrated that their properties matched those of light waves. His theory provided a unified description of electromagnetism and laid the foundation for modern physics.
An optical modes refer to a specific solution of the Wave Equation which satiates the boundary conditions.
we see the amplitude of the wave and carefully note it then we see the starting from the x axis and then write the equation in sin form
Hertz invented the electromagnetic wave to test James Clerk Maxwell's theory that light is a form of electricity. Hertz created electric waves and showed that they operated like light.
Maxwell developed the wave theory of all forms of electromagnetic radiation.
Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light. Therefore, he also suspected that light was an electromagnetic wave. This was confirmed later.Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light.

The speed of a wave is defined by the equation v = fλ, where v is the speed of the wave, f is the frequency of the wave, and λ (lambda) is the wavelength of the wave.
