What is one property of a wave that determines how much it will diffract when it encounters an obstacle? -speed -amplitude -polarization -wavelength suppose two waves collide, and the temporary combined wave that results is smaller than the original waves. what term best describes this interaction? -diffraction -destructive interfernce -standing wave formation -constructive interfernce the formation of a standing wave requires -the traveling of a wave for a long distance -constructive interference between two waves of slightly different frequencies -that refraction and diffraction occur at the same time in a wave -interference between incoming and reflected waves
