haha awesome! Thanks for the guidance... All the best :)

so, the vibrations resemble a snake slithering (in a sine wave fashion) on the road right? The lens would then have to be polarized vertically, or perpendicularly to the "parallel vibrations" in order to minimize vibrations. Did I hit that one on the head? PS. I am soo getting a polarized pair...

Ahhhhh ok :) Hummmm.. this is interesting actually. Makes me want to get a pair of polarized sunglasses! Ok, so this means that the predominant parallel vibrations as they put it, coming off the road are somehow already "polarized" in a sense? This means that the sunglasses are polarized in such...

Thanks for the reply :) Actually no I never owned a pair. I don't see how it is reflected parallel to the surface. Light is reflected in ALL directions from what I understand isn't it? If a surface is going to reflect light predominantly parallel to itself then the source of light must also be...

Hi Dick, Could they be referring to linear type polarization filter vs circular type? We did not cover circular or linear so I would be hard-pressed to think that this is what they meant by it... but I think ur right, "DIRECTION" is what they meant by it... so basically they are saying that...

Homework Statement Light reflecting off most outdoor surfaces such as roadways and bodies of water have less vibrations perpendicular to the surface than parallel to it. What type of polarizing lens would be the most effective at minimizing the glare off these surfaces?2. The attempt at a...

Hahaha! Nice try MK ;) Actually this question arose from me DOING my homework on particle accelerators. Now I am just curious about other technologies. Anything with a circuitboard is more electronics with a small component of electromagnetism isn't it? Is this all we have in the form of...

Hi all, Examples of electromagnetic tecnologies that I am familiar with are particle accelerators, maglev trains, and mass spectrometers... however, I am curious as to what other tecnologies currently exist that involve electromagnetism. Thanks! Cheers, Matts

Makes sense :) Thanks for the input Hootenanny. All the best!

I remember being told as a youger boy that water turns according to which hemisphere of the Earth it is on... was pissed when I found out it wasn't true :)

Hi Hootenanny, thanks for the reply :) So basically how do I demonstrate conservation of momentum for a system in which there is collision between a biker and pavement (earth)? Is it safe to consider the Earth as stationary given that it has rotational and translational movements? What happens...

I have a fundamental question regarding conservation of momentum (not homework). So if we have a system of 2 balls, identical in size and weight, one of which is initially stationary until hit by the other ball. We have the following: m1v1 + 0 = 0 + m2v2 or v2 = v1 and therefore...

awesomeness... thank you

Hummm, photography 101 tells me that the camera with a small pinhole is going to produce am image with a large Depth of Field but at the cost of a darker image. The large pinhole will allow in a great amount of light but at the cost of a more shallow DOF. Not sure about the several pinholes one...

Update: So Basically, I know now that the force of the spring is in fact internal. But, if there is no velocity on the y-axis why would I have to calculate it? And I on the right path performing calculations for the x-axis only? Cheers
