Impedance is the total, or effective, opposition to current that takes into account both resistances and reactances.
 
  Indicate whether the statement is true or false

Question 2

Why would it be impossible to obtain interference fringes in a double-slit experiment if the separation of the slits is less than the wavelength of the light used?
 
  What will be an ideal response?

Answer to Question 1

TRUE

Answer to Question 2

In no direction could a path difference as large as one wavelength be obtained, and this is needed if a bright fringe, in addition to the central fringe, is to be observed.
