Diffraction is the spreading of light that takes place when it pass through a thin slit or small hole or passes by an obstacle
Answer:
Diffraction is the spreading of any kind of wave that take place upon passage of that wave by an obstacle or through a thin slit or small hole. Light is a type of wave so the statement is true.
Coupling factor: If all the flux of a primary coil links with all the turns of a secondary then 100% coupling exists. Sometimes it is more convenient to use a coupling factor
