How does refractive power of a lens change if its radius of curvature decreases? - The power increases How does refractive power of a lens change if its radius of curvature increases? - The power decreases What is radius of curvature in case of a lens? - 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? - Refractive power will increase Calculate the refractive power o...

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...
