. On passing through A, only the vertical vibration of the string appears and these continue to go through B and come out finally. When the slit of board B is placed perpendicular to A, no vibrations appear to come out of B, although vibrations appear in the region between A and B. We therefore say..

Constructing and interpreting graphical displays of distributions of univariate data: Dotplot, stemplot, histogram, cumulative frequency plot Center and spread Clusters and gaps Outliners and other unusual features Shape Summarizing distributions of univariate data: Measurin..

In the preceding sections, the motion of a body when acted upon by a constant force was considered. The motion is one of constant acceleration. In this section, the motion of a body subjected to a variable force is considered. There is one common and important type of non-uniformly accelerated moti..

transmitted by T 1 and T 2 remain unaffected. However, when axes of the two crystals are at 90 0 to each other, light is completely cut off. This establishes that light waves are transverse in character. When unpolarised light is seen through a single crystal (polaroid), intensity of transmitted li..

-rays. If the X-rays are analyzed for the intensity and the wavelength, one can draw a intensity V r m s wavelength graph as show in the figure. In the graph show we find that X-rays are emitted only after l = 40 pm below which there is no emission. This is called as threshold wavelength...

Principles of Light Modulation - Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded information (Morse cod..
