yes! The answer is 601 nm.
If you take the wavelength and times it by the index of refraction of water (1.33), you get 150.29. Multiply that by 4 and get ~601 nm. Don't know how that fits into the formula of 2T = wavelength / something (in example its over 4 or 2, don't know how to get that...
Homework Statement
A thin layer of water (n=1.33) is surrounded by air what wavelength of light will not be transmitted through the water at the point where the water is 113 nm thick?
The Attempt at a Solution
- In phase
- Path difference of 2T.
- Constructive Interference

A quasar is moving away from the earth with a speed of 0.850C. It emits a proton that eventually reaches earth, and is travelling at a speed of 0.519C relative to the earth. How fast is the proton moving relative to the quasar?
Is this answer as simple as it seems?
is the answer simply...
i don't know what it means? it's on the formula sheet there is an example using it. all i want to know is the speed of the proton relative to the quasar...
QUASAR<-0.85c-<QUASAR "shoots" PROTON>0.519>PROTON <EARTH>
the velocities are relative to earth.
THERE! I DREW IT OUT :) Does...

3.5 1.9 0.9
5.4 2.8 -2.1
8.2 0.7
8.9
see what I mean? absolute value algorithm ends with 0.6
0.6
how do i finish it and get the mass? is 0.6 grams the mass?:S
YIIIIIIIIIIP i did it without the negatives and i got 0.9, 0.3, 0.9 .. which equals 0.6, 0.6. BUT if i use negatives for the last step it would be 0.6 - (-0.6) = 1.2 g! is that a good guess? or should i stick with 0.6?
