Final answer:
The maximum strength of the B field in an electromagnetic wave can be calculated using the relationship between the E field and the speed of light. In this case, the maximum E field strength is given as 1000 V/m. Plugging these values into the equation, the maximum B field strength is approximately 3.33 x 10^-6 T.
Step-by-step explanation:
The maximum strength of the B field in an electromagnetic wave can be calculated using the relationship between the B field and the E field. The B field strength is given by B = E/c, where E is the maximum E field strength and c is the speed of light. In this case, the maximum E field strength is 1000 V/m. The speed of light in a vacuum is approximately 3 x 10^8 m/s. Plugging these values into the equation, we get:
B = 1000 V/m / (3 x 10^8 m/s) = 3.33 x 10^-6 T
Therefore, the maximum strength of the B field in the electromagnetic wave is approximately 3.33 x 10^-6 T.
