The amplitude of the electric field for a certain type of electromagnetic wave is 570 N/C. What is the amplitude of the magnetic field for that wave? (c = 3.00 × 108 m/s)

Given Information:  

Amplitude of the electric field = E =  570 N/C

Speed of light = c = 3.0x10⁸ m/s

Required Information:  

Amplitude of the magnetic field = ?

Amplitude of the magnetic field =  1.90x10⁻⁶ T

Explanation:

The relation between the amplitude of the electric field and magnetic field is given by

B = E/c

Where c is the speed of light

B = 570/3.0x10⁸

B = 1.90x10⁻⁶ T

Therefore, the amplitude of magnetic field is 1.90x10⁻⁶ T

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
