To find the amplitude of the electric field (E₀) in a laser beam with a given intensity (I), we can use the relationship between intensity, electric field amplitude, permittivity of free space (ε₀), and the speed of light (c). ### Step-by-Step Solution: 1. **Understand the Intensity Formula**: The intensity (I) of an electromagnetic wave is given by the formula: \[ I = \frac{1}{2} \epsilon_0 E_0^2 c ...
