An electromagnetic wave is travelling in \(x\)-direction with electric field vector given by, \(\overrightarrow E = {E_0}\sin (Kx - \omega t)\widehat j\). The correct expression for magnetic field vector is
The electromagnetic wave is propagating along \(x\)-axis and \(E\) component is along \(y\)-axis. So B component should be along \(z\)-axis. The correct option is (3).

Assertion : Radio waves can be polarised. Reason : Sound waves cannot be polarised.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Radio waves exhibit polarization due to transverse oscillations of electric and magnetic fields perpendicular to propagation, while longitudinal sound waves lack polarization as particle oscillations align with wave motion. So correct option is (2).

Assertion : In electromagnetic waves, electric field and magnetic field lines are perpendicular to each other Reason : Electric field and magnetic field vectors do not have any link in these waves.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Electromagnetic waves, characterized by sinusoidal electric and magnetic field variations, propagate in free space without a medium. The two vector fields are perpendicular to each other.So correct option is (3).

The source of electromagnetic wave can be a charge.
1 Moving with a constant velocity
2 Moving in a circular orbit
3 At rest
4 Moving parallel to the magnetic field
Explanation:
Accelerated charges can produce electromagnetic waves. Since a charge moving in a circular orbit is accelerating continuously, it will emit \(EM\) waves.
