Explain the Diagramming Waves?
There are two ways that waves can be indicated in a two-dimensional diagram. Parallel lines can be drawn that are meant to show the position of the peak displacement of the waves. This method is most commonly used to show water and sound waves, but it also is used for light, especially when we start talking about interference and diffraction.
Alternatively, rays may be drawn perpendicular to these wavefronts, indicating the direction of travel of the waves. Reflection of waves from a flat surface requires that the angle of incidence, θi (measured from the incoming ray to the normal of the reflective surface) must equal the angle of reflection, θr (measured from the normal to the reflected ray).
What are the needs of light sources for fibre optic communication? Light sources for fibre optic communication should meet certain given requirements as illustrated below: a
The force is in Newton The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 10 3 kg/m 3 ),
ISOLATED SYSTEM: "When a number of bodies are like that they can exert force upon one another and no external agency exerts a force on them, they are said to form an isolated s

What is the echo of the launched pulse? Any discontinuity into the medium of propagation of an ultrasonic pulse provides rise to back-reflection that travels back to the input

Who are the best system integrators? Being fairly the opposite of fiber optics manufacturers, system producers are generally small companies. In this case size has the opposite
Presumptuous that it is understood that the object is in front of the mirror and anything on the other side of the mirror is behind the mirror is the following statement sufficient
Doppler effect (C.J. Doppler) Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if reced
