Consider the following scenario: Today when I switched on my radio, I received a radio
programme at a frequency of 9400KHz, from a radio station far away from Oman.
(i) Can you calculate and tell me what is its operating wavelength ?
(ii) What type of wave propagation and what type of modulation are used by these waves?

I read this great answer to this question: Numerical software to manipulate a light beam in its plane wave representation? The main thing that I am trying to clear in my head is the following: Given that plane waves are eigenmodes of maxwell's equations in free space in the absence of sources, shouldn't I be able to use this to propagate a planar e/m field exactly (ignoring aliasing effects)? For example I know the field that exits in the x,...

SITUATION HYPOTHESIS TESTING TOOL: I work at a radio station that also has an app, where you can upgrade to a premium product. The premium app makes it possible to swipe away more songs you don’t like. The data will be relating to the age of the costumers buying premium packages. (The age is very important for our radio station, as we are targeting a very young audience). Null Hypothesis & Alternate Hypothesis: H0 : μ = 20 H1: μ...

1. You are being hunted by a raptor. It corners you, and begins to charge, qt a velocity of 20 m/s. You have constructed a trap. It consists of a trip wire that will knock the raptor down and transfer all of its KE to a phaser rifle that requires 80 kJ of energy to fire directly at your foe. If the raptor has a mass of 150 kg, will the rifle gain enough energy to fire? a)no b)not enough...
