A - the amount of time needed to travel the distance
The formula for speed is distance/time and the unit is m/s. Therefore you divide the distance travelled by the time it took to travel it.
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
In general, pitch increases more rapidly than frequency for tones below 1000 Hz and less rapidly for tones above 1000 Hz. That is, for frequencies above 1000 Hz a greater change in frequency is needed to produce a corresponding change in pitch.
