Electromagnetic Diagram of 4 Antenna Array - Philip's Question

AI Thread Summary
A user is seeking an electromagnetic diagram of a four-antenna array arranged in a square, with edges spaced one wavelength apart. The discussion clarifies that the term "electromagnetic diagram" was coined by the user to explore how the antennas' waves interact. There is uncertainty about the type of antennas being referenced, as the original question does not specify. The user speculates that the strongest combined radiation may occur diagonally from the corners due to constructive interference from three antennas. The conversation highlights a lack of detailed information on antennas in the user's reference material.

Just wondering if anyone happens to have an electromagnetic diagram of how a four antenna array would look. Provided that all four antennas’ form a square and edges are one wavelength in distance?
Thanks

What is an "electromagnetic diagram?" What kind of antennas? Dipoles? Why would you want to make a square out of them?

sorry I kind of made up the term "electromagnetic diagram", I just wanted to see how the electromagnetic waves interact with each other(being from the 4 different antennas).


"What kind of antennas? Dipoles?"
The homework problem does not make mention of this

"Why would you want to make a square out of them?"
The question is asking in what horizontal direction will the combined radiation be the strongest at great distance away.

Unfortunately my book does not go into dept about antennas, it is in a chapter regarding physical optics.

Thinking about it this morning, I'm guessing the direction where the strongest combined radiation will be diagonally from the corners. I'm figuring this because you would have 3 antennas contributing in constructive interference?

are you referring to a diagram of the antenna array's directivity?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
