Working Principle of an Ordinary Microscope: In an ordinary microscope, the object is viewed due to differences in colour intensities of the specimen. To create the colour intensities, the specimen is first stained with suitable dyes which will impart specific colour. In an ordinary microscope, the contrast is obtained when […]

Alpha vs Beta vs Gamma Rays Unstable atoms on radioactive decay emit particles such as alpha particles, beta particles and gamma rays. These are energy particles, and by producing these energy-rich particles the unstable radioactive atom tries to attain atomic stability. The present post discusses the chemical, physical and biological […]
