Does perpendicular incident light slow down through glass? When light travels through glass at a perpendicular angle, there is no refraction and hence no bending. If it slows down through glass, does that mean that red will emerge first and violet last?

The question reads: "Consider the surface given by the equation x^3 + xy^3 - z^2 = -4 The point p = (1,2,3) lies on this surface. Give a vector that is perpendicular to the surface at p?" I'm not too confident about this question although there is a theorem in my notes saying: if p...

I don't know if I'm having a brain fart or what but I'm drawing a blank...:smile: What is the slope of a line perpendicular to x - 3y = 9? Notes: Perpendicular lines have slopes that are negative reciprocals of each other. Example: So, if the original line has a slope of -3/2, the...

Determine whether the point W(2,-1) lies on the perpendicular bisector of line segment UV, endpoints U(3,5) and V(-3,-1). Explain and justify your answer. I can't figure it out, if someone could, it would be a pleasure! (it is a grade 10 question)

I have a curve -\sqrt {2x^3 } on which I'm supposed to draw a tangent that is perpendicular to the line \[y = \frac{4}{3}x + \frac{1}{3}. I know that this tangent must have a "steepness" of -3/4 in order to make it perpendicular, but how do I now find the point on the graph?

How would you go about finding a perpendicular vector, to two 3 dimensional vectors? One way, I solved is using the cross product of the two vectors. Splitting the i's j's and k's up and solving using a determinent. But, what's another way to do it?

solving perpendicular oscillation problems-- lissajous Hi all. Ok, I am not getting how we're to solve perpendicular oscillatory systems. How do the variances in frequency, and phase play into the drawing/solving of these systems? Oh, and this is not a trig class I'm doing. It's an...

The component of a force in a perpendicular direction is given by F Cos 90 and is 0. But when one rides a bycycle and stops paddling before and after taking a 90degree turn, the bycycle continues to move forward. What might be the explanation?

What is the difference between these terms? In what context do they apply to? How important is it that we treat them differently?

Hi, I suppose my question has to do with planes in general, rather than just tangent planes. Say you have a plane given by the equation z=\frac{\partial f}{\partial x}(x)+\frac{\partial f}{\partial y}(y). How would you find the equation of the plane perpendicular to this one? Thanks...

1. What reqiurements does a quadrangle need that all the perpendicular bisectors of the sides crosses in one point?? 2. And how can you proof it? To 1. - I think each angle have to be 90° but I can't proof it :blushing:

Kinda confused on this one becuase of the time difference involved A train leaves a station going south at 60 km/hr at 10:00. Another train heading due west reaches this station at 11:00. The latter train was traveling at 45km/hr. At what time are they the closest? To start with the 45...

just a simple question: are perpendicular lines diff from bisector lines? if so, how are their "rules" different?

Dear Friends, I want to indicate a question on photons. Imagine that a photon goes in a direction and hits in a mirror to 45º. This photon is later observed like it has 90º respect its original direction. Well, now imagine that this mirror is closed in a black box, and you don't know...

Does this concept is connected with a pure geometry (of space)?. Thus each dimension is perpendicular at all another. It is simple for presenting graphically up to three dimensions: point, line, square, cube and ….. Further it is much more difficult. What a physical sense of...

If you have a 3d vector, how do you find out the perpendicular vector to this (the normal plane and stuff)? I know that the scalar product has to be 0, but surely that leaves hundreds of ones that would do that, as 2 of the 3 numbers can be chosen and the last one changes the value to 0.
