Using the doppler waves simulation set the unshifted wavelength of the light to 415 nm. set the v/c slider to -0.017 and start the simulation, pausing after waves reach the far side of the screen. with the simulation paused use the distance indicator in the simulation to measure the distance between two successive crests along the dotted line to the right of the moving object. this distance is the apparent wavelength of the light λa.

λa =

using the relationship determine your measured v/c v/c (measured with slider at -0.017) = (record your answer to at least 2 significant figures)

now reset the simulation and set the v/c slider to -0.076 and repeat the steps above

v/c (measured with slider at -0.076) = your answer to at least 2 significant figures)

i guess the game developers wanted to give off a more gamey/cartoony feeling without trying to copy fortnite exactly

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
