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).
One of the practical aspects of the Engineering Profession includes the design of industrial equipment. Design could be described as a creative, iterative and sometimes open-ended

Q. What are coherent sources? Two sources are alleged to be coherent if they emit light waves of the same wave length and start with same phase or have a constant phase differ

A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
Fast neutrons can be changed into slow neutrons by certain materials known as moderator's when last moving neutrons pass by a moderator, they combine with the molecules of the mod
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.
Problem The work done by a force as it acts on an object equals the force times the displacement times the cosine of the angle between the force and displacement vectors. a
Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and
