Define science in short.

Why are short waves used in long distance broadcasts?

Which one is not a short wave radiation ?

Consider a point at the focal point of a convex lens. Another convex lens of short focal length is placed on the other side. Then the nature of wavefront emerging from the final image.

In each of the following questions a short passage is given with one of the lines in the passage missing and represented by a blank. Select the best out of the five answer choices given, to make the passage complete and coherent. Next to China, India is the most populated country in the world.... Particularly, rush to technical and higher education has increased as the scope for arts and science has become lesser and lesser due to lack of reforms and up gradation in the course structure and materials according to the developments of the world. Also, qualification in higher education gives added advantage to face successfully competition in the job market.

A uniform string of length 10 m is suspended from a rigid support A short wave pulse is introduced at its lowest end it starts moving up the string the time taken to reach the support is (take g=10m//sec^(2) )

The energy levels of a hypothetical one electron atom are shown in the figure. (a)Find the ionization potential of this atom. (b) Find the short wavelength limit of the series terminating at n=2 (c ) Find the excitaion potential for the state n=3.
