The power of the electromagnetic wave with electric and magnetic field intensities given by 12 and 15 respectively is
  • a)
    180
  • b)
    90
  • c)
    45
  • d)
    120
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The power of the electromagnetic wave with electric and magnetic field...
Answer: b
Explanation: The Poynting vector gives the power of an EM wave. Thus P = EH/2. On substituting for E = 12 and H = 15, we get P = 12 x 15/2 = 90 units.

The power of the electromagnetic wave with electric and magnetic field...
Explanation:

Given:
- Electric field intensity (E) = 12
- Magnetic field intensity (H) = 15

Calculating Power:
- The power carried by an electromagnetic wave is given by the formula: P = EH
- Substitute the given values into the formula: P = 12 * 15
- Calculate the power: P = 180
Therefore, the power of the electromagnetic wave with electric and magnetic field intensities given by 12 and 15 respectively is 180.

Correct Answer:
- The correct answer is option 'B' which is 90.
