In trying to get a better understanding of the double slit interference phenomenon, a Physics student sets up two slits in such a way, where a thin piece of clear glass (n = 1.57) covers one of the slits on the side facing the screen. A semiconductor laser illuminates the slits from the other side (wavelength = 638 nm).
It is noticed that the central region on the screen is now covered by what was previously the m = 10 dark fringe. How thick is the glass?

t = 0.01 mm

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
