![]() ![]() The fact that his Fun Scale resonates so deeply suggests he is on to somethingĮasy enough to understand: one is obvious, and one is ironic. (For example: A failed relationship that neverĬontained much Type One Fun in the first place.) Type Three Fun is no fun at all – not in the moment, Type Two Fun is miserable while it’s happening, but fun in retrospect, Type One Fun is just pure pleasure:Įating a doughnut, or watching a movie, or flying a kite, or skiing in fresh Proposes that fun comes in three flavours. Specific type of fun – what he calls “Type Two Fun.” That if it’s even half as much fun as their last, it’ll be amazing.Ĭrap kicked out of you qualify as “fun”? What you need to understand, says theĬolorado mountaineer and writer Kelly Cordes, is that we’re talking about a Next adventure as soon as they return home and lick their wounds, expecting “This ‘bikepacking,’ ” my friend posted after one very hard day, “is kicking the crap out of us.”Īnd yet, knowing my friends, I suspect that they’ll start thinking about their Theirs was also a bicycle trip, at least nominally, although the couple seemed to be spending as much time carrying their bikes as they did actually riding them. One friend was cycling through the Rockies on a one-speed bike, sleeping rough and grinding it out over high alpine passes the other was traversing the highlands of Iceland with his wife. So, here A and C represent compressions whereas B and D represent rarefactions.Ī longitudinal wave in the air is graphically represented by means of a density-distance graph as shown in Figure 2.Last week, two videos landed in my inbox – field dispatches, from two friends who took off on adventures as soon as COVID-19 restrictions eased. All the points above this line represent greater density and those below this line represent less density of air than normal. In the Density-Distance graph in Figure 2, the horizontal line XY represents the normal density of air. Please note that the wavy line in Figure 2 which represents a longitudinal wave in air, actually shows the variation of the density of air as the longitudinal wave passes through it. figure 2: Density-Distance graph to graphically represent Longitudinal Wave In other words, a longitudinal wave is represented by a density-distance graph (see figure 2). So, a longitudinal wave in an air medium is represented graphically by plotting the density of air against the distance from the source. Thus, when a longitudinal wave passes through the medium, then the density of the medium changes continuously. In a compression, the density of the medium, say air, is high whereas in a rarefaction, the density of the medium is low. ![]() Now, let’s see how a density-distance graph can represent the compression and rarefaction of a longitudinal wave.ĭensity-Distance graph to graphically represent Longitudinal Wave figure 1: A longitudinal wave is represented pictorially by showing the compressions and rarefactions. So, a longitudinal wave is represented pictorially by showing the compressions and rarefactions. When a longitudinal wave passes through a medium, say air, then some of the particles of air get crowded together and form compression, whereas other particles go farther apart and form a rarefaction. Thus, when a Longitudinal Wave travels in the horizontal direction, then the particles of the medium also vibrate back and forth in the horizontal direction. When a Longitudinal Wave, say a sound wave passes through the air, the particles of air vibrate back and forth parallel to the direction of the sound wave. Here, we will see how the Density-Distance graph graphically represents a Longitudinal Wave. In this post, we will study Longitudinal Wave Graphical representation. ![]()
