The electric and the magnetic field associated with an E.M. wave, propagating along the $$\mathrm{Z}$$-axis can be represented by

An electromagnetic wave is propagating along X-axis. At x = 1 cm and t = 18s, its electric vector |E| = 8 V/m, then the magnitude of its magnetic vector is

Choose the correct statement.

The magnetic field of a beam emerging from a fitter facing a flood light is given by

B = 10 $$\times$$ 10^$$-$$8 sin(1 $$\times$$ 10⁷z $$-$$ 3.6 $$\times$$ 10¹⁵t)T. The average intensity of the beam is
