Question 2: 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$$-$$7

Answer

3.14 $$	imes$$ 10$$-$$8

Answer

3.16 $$	imes$$ 10$$-$$7
