Answer:
Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time. An object with no movement at all has a zero speed.
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 = ?
Answer:
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
