Question 3: EM waves

Question

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

Accepted Answer

As we know that, ${E \over B} = c$
so, $B = {E \over c} = {8 \over {3 	imes {{10}^8}}} = 2.66 	imes {10^{ - 8}}$

Answer

2.66 $	imes$ 10
$-$8

Answer

3 $	imes$ 10
