Constructive waves - Study guides, Class notes & Summaries

PHYS 1260 Exam 4 with correctly explained test. Superposition and Interference - correct answers.- same wave + same wave = reinforcement - two opposite waves = cancellation - two similar waves = partial cancellation - interference patterns of overlapping waves from 2 vibrating sources - interference pattern = caused by interference b/w a pair of waves - constructive interference produces bright region where waves reinforce each other (waves arriving in phase) - destructiv...

All of the following are true EXCEPT: a) two waves with identical frequencies must interfere constructively. b) constructive interference is associated with waves that are in-phase. c) out-of-phase waves interfere destructively. d) waves of different frequencies may exhibit both constructive and destructive interference at different times. - ️️A Which of these intensities is the smallest? a) SATP b) SPTP c) SATA - ️️C The effects of soft tissue on ultrasound are called: a) aco...

Sound waves are: a) electric b) mechanical, transverse c) spectral d) longitudinal, mechanical -answers - D The speed of sound of ultrasound in soft tissue is closest to: a) 1,540 km/sec b) 1.54 km/sec c) 1,500 m/s d) 1,540 mm/sec -answers - C Which is not an acoustic variable? a) density b) pressure c) distance d) intensity -answers - D The effects of soft tissue on ultrasound are called: a) acoustic proliferation properties b) dynamic effects c) acoustic pr...

Destructive vs constructive interference - ️️Constructive interference occurs when two waves overlap at the same location at the same point in time ( in phase) and the new combined wave has an amplitude greater than the original two waves. Destructive interference occurs when the waves are out-of-phase and the amplitude of the new wave is less than one of the original waves What is dynamic frequency tuning? - ️️A pulse from a transducer contains a wide range of frequencies (broad b...

Sound - a form of mechanical energy produced by vibrating objects that is transmitted by pressure waves through a medium - needs a medium with particles to travel/propagate - cannot travel in a vacuum (medium with no particles) Mechanical Energy - has to be transmitted - propagated from one point to another - need a medium (can't propagate without a medium) Cycle - used to describe any changes in particle motion (particle displacement, density, or molecules, pressur...
