Solution and Explanation
Coherent Sources
Definition of Coherent Sources
Two sources are said to be coherent if they emit light waves of the same frequency, wavelength, and constant phase difference.
Explanation
Two independent sodium lamps cannot act like coherent sources because their emissions are not phase-locked, and their phases vary randomly over time.

- An electric dipole of dipole moment \( 1.0 \times 10^{-12} \ \text{Cm} \) lies along the x-axis. An electric field of magnitude \( 2.0 \times 10^4 \ \text{NC}^{-1} \) is switched on at an instant in the region. The unit vector along the electric field is \( \frac{\sqrt{3}}{2} \hat{i} + \frac{1}{2} \hat{j} \). The magnitude of the torque acting on the dipole at that instant is:
