Particles and waves should behave differently when they encounter the edge of an object and form a shadow (Figure 1). The mouse cursor can be employed to drag the opaque light stop back and forth in front of the oncoming waves or particles. Light waves interact with the light stop by diffracting (or bending) into the shadowed region behind the opaque barrier. Prior to becoming a wave, the particles align themselves in waves. The Particle/Wave slider, located beneath the light stop, can be utilized to morph the beam of particles into a planar wavefront. Upon encountering the stop, particles are either deflected (not illustrated) or pass by the object undeviated. The tutorial initializes with particles of monochromatic red light (photons) impacting the surface of a opaque light stop with an incident angle of approximately 90 degrees. This interactive tutorial explores how particles and waves behave when diffracted by an opaque surface. The opposing view holds that light is composed of a steady stream of particles, much like tiny droplets of water sprayed from a garden hose nozzle. One point of view envisions light as wave-like in nature, producing energy that traverses through space in a manner similar to the ripples spreading across the surface of a still pond after being disturbed by a dropped rock.
