An electromagnetic wave in a vacuum has an instantaneous magnetic field (5.00) strength of 0.000000785 T at a certain point. What is the instantaneous electric field strength of the wave at this point?

Respuesta :

Answer:

electric field strength is 235.5 V/m

Explanation:

given data

magnetic field (5.00)

strength = 0.000000785 T

to find out

electric field strength

solution

we will apply here formula that is

electric field strength = strength ×  speed of light

put here all these value in equation 1 we get

here speed of light = 3 × [tex]10^{8}[/tex] m/s

electric field strength =  strength ×  speed of light

electric field strength = 0.000000785 ×  3 × [tex]10^{8}[/tex]

electric field strength = 235.5

so electric field strength is 235.5 V/m
