Basic equation: X/L = Wavelength/D

if Wavelength = XD/L how do I solve for X, D , And L?

Please Help
 
Mathematics news on Phys.org
X = WL/D

D = WL/X

L = XD/W

Simple questions with simple answers. Glad I could help!
 
thanks a lot!
 
Not only am I glad to post, but guess what.

This is OFFICIALLY my favorite post here ever. The dudes asks a question. It's math, which is far above science. The question ( or set of 3 questons) have one and only one answer in his setup. There is no room for error.

Ya damn did the best and most irrefutable post ever. MY FREAKIN FAVORITE!

PS: Needless to say, watch someone come here and refute it. That persons brain surely needs some help. Secondly, someone will jokingly refute it cuzz I said this, and to that person I say "I speeet on you"
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
