A 500 W lamp radiates power isotropically (thus unpolarized) with an efficiency of 80%. Calculate at the distance r = 5 m: • the intensity of I, • the maximum values Eo of the electric field and Bo of the magnetic field, • the force F exerted on a disk of radius a = 5 cm, perfectly reflecting orthogonal to the direction of propagation of the waves.
