Consider two gratings with the same slit separation. The only difference between the two gratings is that one grating has 5 slits and the other 10 slits. Both gratings are illuminated with a beam of the same monochromatic light. Which of the following statements are true?

Check all that apply.
a. The grating with 5 slits produces the greater separation between peaks.
b. Both gratings produce peaks of the same width.
c. The grating with 10 slits produces the greater separation between peaks.
d. Both gratings produce the same separation between peaks.
e. The grating with 10 slits produces better-defined (narrower) peaks.
f. The grating with 5 slits produces better-defined (narrower) peaks.

b. Both the gratings will produce the same separation of peaks.

e. The grating with 10 slits will produce better-defined(narrower) peaks.

b) phosphorus pentoxide

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
