JEE Main 2026 Physics question
An electromagnetic wave travels in free space along the x-direction. At a particular point in space and time, T is associated with this wave. The value of corresponding electric field at this point is V/m.
Answer: (B)
Solution
|E| = c|B| = 3×10⁸ × 2×10⁻⁷ = 60 V/m. For propagation along +x with B along +y, E
