A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. For example, the nuclide symbol for uranium-238. The total charge is conserved during…

This lecture introduce on Nuclear Chemistry. In this lecture we will look at two types of nuclear reactions. Radioactive decay is the process in which a nucleus…

Major objective of this lecture is to present on Ultraviolet Radiation. Ultraviolet Radiation(UV) is simply one form of energy coming from the sun. Even though you may…

Space radiation is composed of energetic charged particles (atoms with all of the electrons striped). Astronauts are exposed to secondary neutrons as well. The radiation environment of…

The aim of this lecture is to present on Ozone Hole. Ozone (O3) forms under the effect of UV light in the stratosphere. Ozone can also form in…

Prime purpose of this lecture is to present on Volcanic Ozone Hole. An “ozone hole” could form over the North Pole after future major volcanic eruptions –…

Basic purpose of this lecture is to present on how is Ozone Formed. UV radiation strikes the O2 molecule and splits it, atomic oxygen associates itself…

General purpose of this lecture is to present on Ozone Hole. Dramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970s…

Properties of waves include speed, frequency and wavelength. All light travels at a speed of 3 s 108 m/s in a vacuum. The electromagnetic spectrum includes,…

The aim of this lecture is to present on Temperature Measurement. Temperature is a physical property of a system that underlies the common notions of hot and…

Electromagnetic waves come in many wavelengths and frequencies. Each one is useful in different ways. The electromagnetic spectrum is the range of all EM frequencies. The…

The electromagnetic spectrum is the complete spectrum or continuum of light including radio waves, infrared, visible light, ultraviolet light, X-rays and gamma rays. An electromagnetic wave…
