Intensity of sunlight is observed as

0.092\,W{m^{ - 2}}

at a point in free space. What will be the peak value of magnetic field at that point?

({\varepsilon _0} = 8.85 \times {10^{ - 12}}{C^{ - 2}}{N^1}{m^{ - 2}})

View answer and explanation

Correct option: A

2.77 \times {10^{ - 8}}T

Option A (

2.77 \times {10^{ - 8}}T

) is correct because it is calculated using the relationship between intensity, electric field, and magnetic field in an electromagnetic wave.
