Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave. Further, the behavior of particles in quantum mechanics are described by waves.
Step Three: Prepping the Patties. We prefer a 1/3 pound to 1/2 pound patty for the best grilling. This allows us to establish a delicious crust on the outside of the burger while keeping the inside a perfect Medium (160ÂºF). If the patties are too thin, this is much more difficult to do.
The USDA recommends cooking burgers to an internal temperature of 160F, at which point it will probably not have any pink in the center - but a burger cooked to 140F (medium rare) may also not have pink in the center! Color is not a reliable way to judge doneness.
