The scattered light intensity is proportional to the square of the time average of the electric field (20) where 〈〉 denotes the time average. In order to measure the very small optical linewidths indicated in Section 7.2.1 optical mixing techniques are employed since dispersing optical instrumen...
In semiconductor detectors interacting gamma rays deposit energy in the detector material, creating electron-hole pairs that are collected following application of an electric field to the material. Semiconductors are far superior spectroscopically to scintillators, due to their relatively low threshold ...
Step 3: Consider the Energy of Electromagnetic WavesFor electromagnetic waves, the energy can be represented in terms of the electric field (E) and magnetic field (B). The energy density (u) of an electromagnetic wave is given by:u=12ϵ0E2+12B2μ0However, in terms of intensity, we ca...
What is meant by electric field intensity? How do we measure the speed of light? Answer the following question. What do the various colors displayed in the flame of a burning log represent? Why is fire hot? Explain with example. What is magnetic intensity?
where 𝐼(𝑡)I(t) is the optical intensity, 𝐸(𝑡)E(t) is the electric field strength, 𝐸∗(𝑡)E*(t) denotes the complex conjugate of the electric field intensity, and 〈⋅〉〈⋅〉 denotes averaging over time. A basic dual-telescope intensity interferometer is describ...
In mathematical terms, luminous intensity is defined as the quotient of the elementary luminous flux by the elementary solid angle in which it is propagated. It is expressed in candela (cd). In addition, as sunlight is not perceived equally by the eye depending on the wavelength at which it...
