Is scattering a type of diffraction? For any type of wave, one way to define diffraction is the spreading of waves, i.e., no change in the average propagation direction, while scattering is the deflection of waves with a clear change of propagation direction. The intensity distribution of this wave yields what is commonly called the […]

What is the resistance of a wire if the length is doubled?
What is the resistance of a wire if the length is doubled? What happens to resistance when length is doubled? From the equation, we understand that resistance is directly proportional to the length of the conductor and inversely proportional to the crossectional area of the conductor. Doubling the length doubles the resistance. What happens to […]
