The maximum magnetic field strength in the light waves striking the wall is approximately 2.18 × 10^-4 T.

The maximum magnetic field strength in the light waves striking the wall can be calculated using the formula:

B = sqrt(2μ0I)

Where B is the maximum magnetic field strength, μ0 is the permeability of free space (4π × 10-7 Tm/A), and I is the average intensity of the light waves (343 W/m2).

Plugging in the values, we get:

B = sqrt(2 × 4π × 10-7 × 343)
B ≈ 2.18 × 10-4 T

Therefore, the maximum magnetic field strength in the light waves striking the wall is approximately 2.18 × 10-4 T.
