An electromagnetic wave of wavelength 435 nm is traveling in vacuum in the -x-direction. The electric field has amplitude 2.70 * 10^-9 V/m and is parallel to the -axis. What are (a) the frequency and (b) the magnetic-field amplitude? (c) Write the vector equations for E(z) and B(z). The wave is traveling in the positive x-direction, the same direction as E x B. i x j = k j x k = i k x i = j j x i = -k k x j = -i i x k = -j i x i = j x j = k x k = 0 Sinusoidal Electric field: Electric-field magnitude: E(x) = E_max * cos(kx - wt) Number propagating in the angular +x-direction: B(x, t) = B_max * cos(kx - wt) Frequency: Magnetic field: Magnetic-field magnitude: B = B_max E: y-component only B: z-component only

A charged particle oscillates about its mean equilibrium position with a frequency of $10^{9} \mathrm{~Hz}$. The electromagnetic waves produced $\quad$ [NCERT Exemplar] (a) will have frequency of $10^{8} \mathrm{~Hz}$ (b) will have frequency of $2 \times 10^{4} \mathrm{~Hz}$ (c) will have a wavelength of $0.3 \mathrm{~m}$ (d) fall in the region of radiowaves
