A wave solution to Maxwell's Equations is given by E⃗ =E0xˆcos(5.0 z)cos( 1.03e11 t) where z is measured in centimeters and t in seconds. (a) What is the wavelength (in rad/meter) of the wave? (b) What is the index of refraction, n, of the medium? (c) The...

Write down the electric field and associated magnetic field in vacuum for a traveling plane wave with the following properties. The amplitude of the electric vector is E0 and the frequency is ω. The radiation is linearly polarized in the y-z plane at an a...

Ey=E0sin(kx−ωt), Ez=4E0sin(kx−ωt), the magnetic field can be written in the following way B =[ sin(ωt+(−1)bBkx)(cBxˆ+dByˆ+eBzˆ)] In other words: Bx=cBsin(ωt+(−1)bBkx), By=dBsin(ωt+(−1)bBkx), Bz=eBsin(ωt+(−1)bBkx) Find : dB . Express it in terms of E0, c e...

At the upper surface of the earth's atmosphere, the time-averaged magnitude of the Poynting vector is referred to as the solar constant and is given by </S/>=1.35×103W⋅m−2 . (a) If you assume that the sun's electromagnetic radiation is a plane sinusoidal...

An optical fiber is a flexible, transparent fiber devised to transmit light between the two ends of the fiber. Complete transmission of light is achieved through total internal reflection. This problem aims to calculate the minimum index of refraction n o...

The digits of a three digit number A are written in the reverse order to form another three digit number B. If B > A and B – A is perfectly divisible by 7, then which of the following is necessarily true? 1. 100 < A < 299 2. 106 < A < 305 3. 112 < A < 311...

Uncle Bert was making porridge in a cylindrical pan of diameter 24cm. The spoon he was using is 26 cm long. It accidentally falls and sinks into the porridge. Calculate the minimum volume of porridge necessary to hide the spoon. You may ignore the volume...

hw did u get dis ?? The volume of porridge is thus at least 1440π

correct answer is 2. 106 < A < 305
