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.
Though any temperature under 160Â° F (71Â° C) -- or 165Â° F (74Â° C) for ground poultry -- is not considered safe for ground meat (USDA Guidelines), here is a list of cooking times for varying degrees of doneness for burgers: 1  Rare: 120 to 125. 2  Medium Rare: 130 to 135. 3  Medium Well: 150 to 155.  Well Done: 160 to 165.
