Projection Definition and 409 Threads

URGENT Can you please help! Hello, I have just finished what seems like an infinite amount of questions for this lab report. 2 of them I am just not sure how to proceed. Any help would be appreciated. Question 1: In a film projection apparatus, it is desired to produce pictures 12 ft...

How can I find the projection of the vector (2,2,1) on the plane that has the equation z=x-y?

hi, i am in need of help pretty quickly here.i will have to design a projector design using a fresnel lens and the projection lens.i need to find and derive the equations for the lenses and calculate the distances between the lenses and the lens and the screen. this is what i require to have...

A problem on my quantum homework assignment this week has to do with the projection operator P = |a><a| I've been asked to show that P^2=P, and then give the eigenvalues of P and then to characterize its eigenvectors. The first part is easy enough: P = |a><a| so P^2 = |a><a||a><a| =...

Hi all ! I'm currently studying time projection chambers and I am wondering how the energy of the incident particle (the one that ionizes the gas in the drift chamber) is calculated from the measured signals. Does anyone have some hints for me ? Thanks a lot for your answers. Best regards

Meaning of "projection" Suppose you have two vectors, U and V. Is it correct that the "projection" of vector U onto vector V is equal to U cos x, where U is the magnitude of vector U, and x is the angle between the two vectors? Specifically, is it correct that the projection of one vector...

The Law of Projection: "No matter where a particular sensory pathway is stimulated along its course to the cortex, the conscious sensation produced is referred to the location of the receptor." ('Review of Medical Physiology', 6th Edition, W.F. Ganong, p. 63) OK, the term 'projection' might...

Hi all, i have recently come up with a problem which i can seem to find a real answer to, i have considered many differnt option, but not sure how to complete on a tight budget. The problem is how to create some sort of 3d projection onto either a screen or just space. Most options seem to...

I think this physics problem deals only with horizontal projection...let me know what you think: A block slides off a horizontal surface with speed Vo. Write an expression relating y, distance fallen, to X, the horizontal distance traveled. i think i can use the horizontal proj. equations...
