Answer:
Explanation:
Given
Electromagnetic radiation = 5.00mW
Convert to watts
5.00mW=5×10^-3 watts
Area = 1.00mm² = 1.00mm×1.00mm
Converting to m²
1.00mm² = 1×10^-3m × 1×10^-3m
1.00mm² = 1×10^-6m²
Intensity = 5×10^-3 watts/ 1×10^-6m²
Intensity = 5 × 10^-3-(-6)W/m²
Intensity = 5×10^(-3+6)W/m²
Intensity = 5×10³W/m²
