The amplitude of magnetic field in an electromagnetic wave propagating along y -axis is 6 . 0 × 10 – 7 T . The maximum value of electric field in the electromagnetic wave is

Options

  1. A2 × 10 15   V   m – 1
  2. B180   V   m – 1
  3. C6 . 0   ×   10 – 7   V   m – 1
  4. D5 × 10 14   V   m – 1

Correct answer

B. 180   V   m – 1

Step-by-step solution

The relation between the electric field and magnetic field is given by E 0   =   c B 0   . The given data is B 0 = 6 × 10 - 7   T c = 3 × 10 8   m   s - 1 Thus, the maximum value of the electric field is E 0 =   3 × 10 8 × 6 × 10 – 7 = 180   V   m - 1 .
