5. PHYSICS OF SOUND - Pennsylvania State University
www.mne.psu.eduThe general plane wave solution for pressure p is made up of waves traveling in both the positive and negative directions: ( , ) 1( ) 2 c x f t c x p x t = f t − + + This physically corresponds to a pressure wave traveling in +x direction and a pressure wave traveling in –x direction. The acoustic particle velocity is related to pressure by ...
NEWTON’S PARTICLE THEORY OF LIGHT
galileo.phys.virginia.eduA wave is a pattern, or shape, or disturbance, traveling through a medium. Examples: Sound is a pressure wave in air. Sideways vibration of stretched string. Football stadium “wave”. As great as Newton was, his particle theory of light has failed. We must find a new model or theory. One other possibility is that light is a wave traveling ...
