Which of the following have zero average value in a plane electromagnetic wave?

(a) along the electric field

(c) The wave delivers momentum p and energy E, p ≠ 0, E ≠ 0

The energy per unit volume contained in electromagnetic waves is U = 1/2ɛE^2 + B^2/2μ If the electric field is represented by a form E_o cos( wt - kx) the energy can...

(i) Standard equation of magnetic field is By = B0sin(ωt + kx)T Comparing this equation with the given equation, we get B0 = 8 x 10-6T, ω = 2 x 1011 rad s-1, k...

(a) Assume the third number = x According to question 2 × 280 + x + 178.5 × 2 = 281 × 5 or, 560 + x + 357 = 1405 or, x +...

(d) Third number = (436 × 5) – (344 × 2 + 554 × 2) = 2180 – 1796 = 384
