Property 1: Electromagnetic waves are transverse in nature. Question 11: How will you investigate the existence of the radiation beyond the red and violet extremes of the spectrum? Photoelectric effect. From this relation between wavelength, frequency and speed of light we can understand that the electromagnetic waves will travel with the speed of light regardless of wavelength and frequency. In electromagnetic spectrum the wavelength (λ) of radio waves is >0.1m. Maxwell showed that electric and magnetic fields move together through space as waves of electromagnetic radiation, with the varying fields mutually sustaining each other. Property 2: They propagate by varying electric fields and magnetic fields, such that these two fields are at right angles to each other and at a right angle with the direction of propagation of the wave. 2-1-4 Quantum Properties of Electromagnetic Radiation Maxwell’s formulation of electromagnetic radiation leads to a mathematically smooth wave motion of fields.
