Plane wave equation

Conclusion. Electromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E = h ν E=h\nu E=hν , we have seen how the frequency of a light wave is proportional to its energy.

The ratio of the electric to magnetic fields in an electromagnetic wave in free space is always equal to the speed of light. This knowledge can then be used to simplify the energy density situation a bit. … c =1√μ0ε0Electromagnetic Waves – The Physics Hypertextbook physics.info › em-waves

Speed, Wavelength, and Frequency Because all electromagnetic waves travel at the same speed through space, a wave with a shorter wavelength must have a higher frequency, and vice versa. This relationship is represented by the equation: Speed = Wavelength × Frequency.
