gamma rays spectrum

While all electromagnetic waves travel at the same speed (i.e., velocity 'c' is constant), the type of their radiation differs in the duration of wavelength and consequently their frequencies. An electromagnetic radiation with a long wavelength will have a low frequency and vice versa. 'The arra..

Gamma decay is the phenomenon of emission of gamma ray photon from a radioactive nucleus...

In 1899, the study of radioactivity was taken up by Ernest Rutherford. He placed a little radium at the bottom of a small lead box and subjected the rays that emerged from it to the action of a very strong magnetic field at right angles to their direction. He found that the rays..

They are electromagnetic radiations like X-rays having very short wavelength, in the range of 10 -10 m to 10 -13 m. They affect photographic plate. They are unaffected by electric and magnetic fields. Their ionizing power is low, (about one hundredth of b - particles). T..

The rays that deflected towards the negative plate consist of positively charged particles and these were called alpha rays. The rays, which deflected towards the positive plate, consist of negatively charged particles and these rays were known as the be..

Beta particles deviate more than alpha particles showing that beta particles are lighter than alpha particles or vice versa. Gamma rays do not deviate as they are electromagnetic waves and hence have no charge..

Before green house effect is studied one needs to know what kind of radiation / sunshine we receive on earth. 'Sunshine' is a common man's term indicating all that we receive from sun. In a shallow perspective of common man, it may simply, mean light. But in a deep scientific meaning of 'sunshine' ..

Above the troposphere is the stratosphere. This zone is rich in ozone. Hence, it is also called ozonosphere. In ozonosphere, oxygen in the presence of sunlight converts to ozone by photochemical dissolution. The ozonosphere completely absorbs short wave solar radiations, such as ultraviolet (uv) r..

In a direct vision spectroscope, a number of thin prisms of crown and flint glasses are alternately placed in a small tube with refracting edges turned opposite to each other. The angles are such that they produce dispersion without any deviation for the mean yellow ray...

Mechanism of Green House Effect - The solar spectrum of electromagnetic waves include energy packed heat generating waves called radiation waves. As they lie beyond red colour waves of visible spectrum, they are also called 'infra-red rays'. These infrared rays..
