Explanation:

Tangential Component of Electric Field Intensity:
The tangential component of electric field intensity is the component of the electric field that lies parallel to the interface between two different media.

Continuity at the Interface:
When an electric field crosses the interface between two different media, it is important to consider the continuity of the tangential component of the electric field intensity.

True Statement:
It is true that the tangential component of electric field intensity is always continuous at the interface. This means that the tangential component of the electric field intensity does not experience any abrupt changes or discontinuities at the interface between two media.

Explanation:
When an electric field encounters an interface between two different media, the tangential component of the electric field intensity must remain continuous to satisfy the boundary conditions. This continuity ensures that there are no sudden changes in the direction or magnitude of the electric field at the interface.

Importance of Continuity:
The continuity of the tangential component of the electric field intensity at the interface is crucial for understanding the behavior of electromagnetic waves and the interaction of fields with different materials.

Conclusion:
In conclusion, it is true that the tangential component of electric field intensity is always continuous at the interface between two different media. This continuity is essential for maintaining the integrity of the electric field and ensuring smooth transitions across boundaries.
