Does Radio Wave Efficiency Improve During Nighttime Tropospheric Enhancement?

AI Thread Summary
Radio waves do not exhibit changes in efficiency based on the time of day. However, radio signals can be received over greater distances at night due to atmospheric conditions. This phenomenon is related to "Tropospheric Enhancement," which affects signal propagation. The discussion highlights that nighttime conditions can improve signal reception rather than the efficiency of the waves themselves. Understanding these factors is crucial for optimizing radio communication.

Radio waves do not work more efficiently or less efficiently depending on the time of day. You probably mean "why can radio signals be picked up at greater distances at nighttime than during the day?"

Thread 'Simple math model for a Particle Image Velocimetry system'

Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
