Answer....

Both Assertion & Reason are true and the reason is the correct explanation of the assertion.

Explanation →

The order of conductivity of various substances is related as -- metals (conductors) > semi conductors > insulators .

Since , silver is a metal therefore its conductivity will be greater than that of silicon which is a semiconductor.

Answer 2

Answer:

According to the de Broglie concept of matter waves, the matter has dual nature. It means when the matter is moving it shows the wave properties (like interference, diffraction etc.) are associated with it and when it is in the state of rest then it shows particle properties. Thus the matter has dual nature.
