Question

Magnitude of the electric and the magnetic fields in a plane electromagnetic wave are related by ______.

Options

• `"B"_0 = "E"_0/("c"pi)`

• `"B"_0 = "E"_0/("c")`

• `"B"_0 = (pi"E"_0)/("c")`

• `"B"_0 = 2"E"_0/("c")`

Answer 1

Magnitude of the electric and the magnetic fields in a plane electromagnetic wave are related by `underline("B"_0 = "E"_0/("c"))`.

Explanation:

`"B"_0 = "E"_0/("c")`, where c is speed of light.
