Maxwell’s equations establish the relationship between $$\overline{E}, \overline{D}, \overline{H}$$ and $$\overline{B}$$ at any point in a continuous medium. When we move from one medium to another, then which of the following statement is correct

At the boundary separating the two media, the tangential components of $$\overline{E}$$ and $$\overline{H}$$ are continuous

At the boundary separating the two media, the tangential components of only $$\overline{E}$$ are continuous

If there are surface charges presenton the bouridary then normal component of $$\overline{D}$$ is continuous

If there are no surface charges then normal componentof $$\overline{D}$$ is discontinous
