Final answer:
To find the average intensity of an electromagnetic wave, you can use the formula: Intensity = (C * E^2) / (2 * μ0), where C is the speed of light, E is the electric field strength, and μ0 is the permeability of free space.
Step-by-step explanation:
To find the average intensity of an electromagnetic wave with a peak electric field of 1900 V/m, we can use the formula for the intensity of an electromagnetic wave:
Intensity = (C * E2) / (2 * μ0)
Where C is the speed of light (approximately 3.00 x 10^8 m/s), E is the electric field strength, and μ0 is the permeability of free space (approximately 4π x 10^-7 T m/A).
Plugging in the given values:
Intensity = (3.00 x 10^8 m/s * (1900 V/m)2) / (2 * 4π x 10^-7 T m/A)
Simplifying the equation, we find:
Intensity ≈ 1.43 x 10^15 W/m2
