1 (a)Describe the difference between longitudinal and transverse waves...[2](b) A loudspeaker emits a sound wave. A microphone is connected to an oscilloscope. The trace produced on the screen of the oscilloscope due to the sound wave is shown in Fig. 1.10mV0.50ms Fig. 1The vertical...
The onset of interfacial instability due to solute transfer between two immiscible liquid phases can be described as the occurrence of an undamped longitudinal wave at their interface. The damping coefficient of such a wave can be expressed in terms of the properties of the interface and the ...
Give a real-life example of Doppler's effect. What is the meaning of coherent waves? Is it impossible to polarize a longitudinal wave? Explain. What would be the outcome if you attempt to produce a longitudinal wave? What sets surface currents in motion?
aThis experimental work shows the possibility to assess the qualitative grain size of the here discussed material from its longitudinal or transverse velocity wave. 这种实验工作显示可能性估计这里被谈论的材料的定性粒度从它的纵向或横向速度波浪。 [translate] aThe original MIMA architecture 原始的MIMA建筑...
Describe what happens when waves reflect off a boundary. a) Amplitude. b) Frequency. c) Wave speed. Reflection of Waves: When a wave incident or strikes the surface/boundary, a part of it returns in the same direction. This return of wave is called a refle...
In a recent research project [1], we use the method expounded in this paper to give carbon emissions in China a more systemic and explicit representation, based on deliberately manipulated longitudinal data from 1997, 2002, 2007 and 2012. The evolvement of the intersectoral embedded carbon flow...
Using a labelled diagram describe the basic elements of a Picture Archival and Communication System (PACS). Explain briefly the relevance and/or purpose of the following in relation to magnetic resonance imaging: (i) The fixed magnetic field (ii) The longitudinal relaxation time constant (T1) (...

A CAN model on the bonded solid-solid interface is depicted. It can be seen from the model that CAN parameter is very sensitive to the bonding strength at the interface. When an incident focusing acoustic longitudinal wave scans the interface in two dimensions, the transmitted wave can be ...
Information deduced from ultrasonic measurements (longitudinal wave velocity, reflection coefficient) associated with other data obtained from X-ray diffraction (XRD), differential thermal analysis (DTA) and thermogravimetric (TG) measurements enable to propose a qualitative description of hydration's ...
