Question

If frequency of electromagnetic wave is … and it travels in air along … direction then the corresponding electric and magnetic field vectors will be mutually perpendicular to each other and the wavelength of the wave (in … ) is :

Accepted Answer

Option B. The speed of electromagnetic waves in air (and in a vacuum) is approximately the speed of light, which we denote as …. The speed of light … is … meters per second. The relationship between the speed of light …, the frequency …, and the wavelength … of an electromagnetic wave is given by the equation:
