Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Mechanical waves require a medium and electromagnetic waves do not.
Hope this helps :)
Answer and Explanation:
Polar compounds are those that have an unequal sharing of electrons, causing one end to be more positively or negatively charged than the other end.
Ionic compounds are those that are made up of a positive ion and a negative ion. Clearly, we can see that if one ion is positive and the other is negative, then that would make one end of the compound more or less positively charged than the other end, which is exactly the definition of a polar compound.
That is why ionic compounds are always polar.
