I have a similar question that I can't figure out part B to, does anyone know how?

Thanks, that looks better now, not perfect but better. :) I get what you did, but I still do not understand why the child would be so much older than the mother when she returns...

Okay, looking over my equation on paper, I found a small error when I calculated the age of the astronaut, she would be 38.358 =37yrs, making her 75.4 yrs old, however this still does not solve my problem, any thoughts? Thanks in advance!

Sorry about the long spaces in between the equations, I'm not quite sure what I did wrong.

Homework Statement A 30 year-old astronaut leaves her newborn child on Earth and goes on a round-trip voyage to a star that is 40 light-years away traveling in a spaceship that is traveling at 0.90 c What will the ages of the astronaut and her child be when she returns? Homework Equations...

Okay, so wave interference will only appear when what? Thanks so much for your help, I really appreciate it!

Okay, I get what you are saying now, the difraction grating is used to separate the different wavelengths. So I use the equation for each wavelength because the different wavelengths mean that they will have different angles for m=1, m=2 etc. Am I on the right track or completely wrong?

No, I know what diffraction is. In my book the explanation and all the examples they give they only use one wavelength. I just don't know what to do with the two...calculate them induvidually?

Okay, I follow to a certain extent...which wavelength do I use? Do I average them?

Homework Statement Light with wavelengths of 520 nm and 630 nm passes through a diffraction grating containing 6000 lines/cm. a. Sketch a diagram of the image produced from m=0 to m=2, labeling the order of each fringe. b. Calculate the angles for the first and second order maxima that...
