light source is incident on a single slit then two closely spaced slits. the emanating light is two in-phase and interfere when arriving at the screen

Ohm's Law
interference
when two waves meet while traveling along the same medium. It can be constructive or destructive
Electric Current
...
thin film interference
The reflected portion of the wave remains in the original medium. The transmitted portion of the wave enters the new medium and continues traveling through it until it reaches a subsequent boundary. If the new medium is a thin film, then the transmitted wave does not travel far before it reaches a new boundary and undergoes the usual reflection and transmission behavior. Thus, there are two waves that emerge from the film
Capacitance Series
diffraction

Right Hand Rule
Place your right hand with the thumb parallel to the wire carrying the current. Point your thumb in the direction of the electrical current in the wire. (Remember: The electric current flows from the plus side of the battery through the wire to the minus side.) Wrap your fingers around the wire. Your fingers will now point in the direction of the magnetic field around the wire. If there are compasses near the wire, they will point in the same direction as your fingers.
