    Light Mirror
AI Thread Summary
To redirect light from directly above to a wall at a 90-degree angle using a mirror, the mirror should be positioned at a 45-degree angle. This is based on the law of reflection, which states that the angle of incidence equals the angle of reflection. The discussion confirms this principle and provides a resource for further understanding. The correct positioning of the mirror will effectively achieve the desired light direction. Understanding these basic optics principles is essential for practical applications.

Hello all,

I've got a question, obviously. I've got a light shining down from directly up above think laser, I want to reflect the light to hit the wall, redirect it 90 degrees. What angle would the mirror need to be to do this? For some reason I'm thinking 45 degrees.

Thanks,

Kevin S. Chambers

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...
