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 is Gravity Force (Fgrav): Force with which the earth, moon, or massively large object attracts another object towards itself. By meaning, this is the weight of the object.
Determine the highest order spectrum which can be seen with monochromatic light of 589.3 nm wavelength by means of a diffraction grating having 15000 lines/inch.
