Final answer:
The maximum magnetic field strength in an electromagnetic wave with a maximum electric field strength of 340 V/m is calculated to be 1.13×10-6 T (1.13 microteslas) using the relationship between the speed of light, electric, and magnetic field strengths.
Step-by-step explanation:
To calculate the maximum strength of the magnetic field (B-field) in an electromagnetic wave, given the maximum electric field (E-field) strength, we use the relationship c = E/B where c is the speed of light in a vacuum (approximately 3×108 m/s). Given the maximum E-field strength is 340 V/m, the formula rearranges to B = E/c.
By plugging in the values, we get B = 340 V/m divided by 3×108 m/s, which simplifies to 1.13×10-6 T or 1.13 microteslas (uT). This magnetic field strength would be the maximum in the given electromagnetic wave.
