STD 12 - 8. Electromagnetic waves — NEET STD 11 Science — Question

Gujarat BoardEnglish MediumSTD 11 ScienceNEETSTD 12 - 8. Electromagnetic waves4 Marks
MCQ
Assertion : Dipole oscillations produce electromagentic waves.

Reason : Accelerated charge produces electromagnetic waves.

  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • ✓
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: B.
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
b
Hertz produced em waves by oscillating  charge between dipolar electric field. A charge moving with non-zero acceleration where both magnetic and electric field are varying emits em waves but this does not explain assertion.
