reflection 21) Soldiers marching on a bridge can cause it to shake and vibrate at a large amplitude. This is the (1.5pts) phenomenon of dispersion doppler effect resonance refraction 22) Standing waves are the result of (1.5pts) interference between waves and their reflection. O dispersion O doppler shift of waves and their reflection O refraction of waves 23) Total internal reflection occurs if the angle of incidence is (1.5pts) is zero degrees. 90 degrees O the critical angle greater than the critical angle 24) When light is traveling from a more dense to a less dense medium at the critical angle of (1.5pts) incidence for the media, it results in constructive interference total internal reflection dispersion a 90 degree refraction Previous 11213|41516 Next
