Interference of waves:
When two waves of similar amplitude and period traveling in the similar medium superpose, they reinforce each other at one point and cancel at others. This phenomenon is called as the interference of waves.
Explain the term 'resistivity' and write its S. I . unit. Derive the expression for the resistivity of a conductor in terms of number density of free electrons and relaxation time.
When Temperature increases,intensity increases,but in some time intensity decreases,Why?
