Optics B/C

I understand the Doppler Effect qualitatively, but could someone please help me understand how to do quantitative problems with it?

Check out the Wikipedia page: http://en.wikipedia.org/wiki/Doppler_effect
It's got some good formulas and links to other sites that let you simulate it.

So do we use the formula for the Doppler Effect in classical physics:



or must we adjust this because we are working with light, rather than sound?

You only need to use the relativistic doppler equation when one of the objects is moving near the speed of light.

Is it true that this year, they're going to make Div B reflect on 2 mirrors for the Laser Shoot as opposed to 1?

Not true. You have the OPTION of using up to 5 mirrors, but nothing in the rules 'makes' you use 2.

...That requires more thought than I had previously given it...better get my partner cracking...

Is this true for Div C as well?

Yup

Do you get different points for using different numbers of mirrors?

[chalker]

Do you get different points for using different numbers of mirrors?

Yes. More mirrors = more points.

Yes. More mirrors = more points.

ahhh
any strategies or hints people are willing to share?? but is the laser shoot pretty much the same concept for division b, with no obstacles? (sorry, haven't gotten the rules manual...)
