    ways to study stars‚ planets and moons in the universe; but the most useful would have to be radio astronomy. Despite this‚ there are some who do argue that optical astronomy is the more useful of the two. Radio waves are a form of electromagnetic radiation and are given and received by many devices we use today‚ such as the radio‚ mobile phone or TV‚ but they have also been detected in space. Radio waves have long wavelengths at a low frequency‚ carrying less energy. Radio

    of an alarmingly rising incidences of cancer and limited treatment options‚ physicians are being forced to look for treatments beyond the conventional ones. In such a scenario‚ Proton Therapy‚ the most advanced radiation technique available‚ is being projected as the Rolls Royce of Radiation Oncology. Unfortunately‚ access to proton therapy is limited for many patients due to the low number of proton therapy centers. Hence‚ many research institutes and hospitals are now investing in proton therapy

    Basic Physics Content with Answers 1. In the absence of air resistance‚ a ball of mass m is tossed upward to reach a height of 20 m. At the 10m position‚ half way up‚ the net force on the ball is A. 2mg. B. mg. C. mg/2. D. mg/4. B is correct‚ as a vector diagram would show. Other choices show carelessness or confusion between force and speed‚ and what constant acceleration means. 2. When you drop a ball it accelerates downward at 9.8 m/s2. If you instead throw it downward‚ then its acceleration

    XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The

    ------------------------------------------------- Refractive index From Wikipedia‚ the free encyclopedia In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. Its most elementary occurrence (and historically the first one) is in Snell’s law of refraction‚ n1sinθ1= n2sinθ2‚ where θ1 and θ2 are the angles of incidence of a ray crossing the interface between two media with
