- Determine the freqency of an atom that vibrates 2.5 x 1010 times in 5.0 seconds.3 - Calculate the Laplace transform of f(t) = sinh(2t)2- If the function describing the change in the electric field and magnetic field in a non-conducting medium is given by: E= E, cos (@t-kz) i , H= H, cos (@t-kz) j Use Maxwell's equation derived from Faraday's law to find the transverse impedance n and then find the impedance if the wave propagates in a vacuum.
- Why is the sky blue at midday?-There is a large amount of water in the air and water is blue, so the sky is blue.-Interstellar dust particles interacting in the upper atmosphere cause a cascade of red, green, and blue light, but only the blue light is bright enough to reach the Earth's surface. -Light is scattered from molecules in the sky. The molecules resonate most strongly at higher frequencies/lower wavelengths, so the greatest intensity of scattered light is at the blue end of the spectrum.-Light is scattered from molecules in the sky but only the blue light reaches the Earth's surface.1- Write the inhomogeneous wave equation for each of the electric field E and the magnetic field H in a medium free of electric charges.i need the answer quickly
