How does refractive power of a lens change if its radius of curvature decreases? - Answer-The power increases How does refractive power of a lens change if its radius of curvature increases? - Answer-The power decreases What is radius of curvature in case of a lens? - Answer-Flattener lens= larger radius of curvature. More rounded lens=lesser radius of curvature. How does refractive power of a lens change if its index of refraction increases? - Answer-Refractive power will increase Calc...

X-rays: Typical diagnostic wavelength and photon energy range. - 100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation is dissipated as ...

Coulter principle. - Answer-The ability to count and measure the size of particles using an electric circuit. Particles are moved through a small aperture, their presence causes a narrowing of the aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * R), when R increases, U increases and pulse is generated. Parts and functions of the Coulter-counter - Answer-- Two spaces with a small aperture in between, capillary (contains the electrolyte sol...
