I have been trying everything under the sun and still can not get the answer right. i used the equation x=n(lambda)L/d L=2.8m Lambda= 657nm d=(475 lines/mm)^-1 am I incorrect with that or no? Because the answer is still wrong for finding the distance between the slits.

and the final units needs to be in cm

I don't know what to do with the theta, since it is not given. and would i say that 1/d=the 475 mm/lines?

dsin(theta)=n(lambda)

Question: Light from a slit passes through a transmission diffraction grating of 475 lines/mm, which is located 2.8m from a screen. What are the distances on the screen (from the unscattered slit image) of the three birghtest (first-order, n=1) hydrogen lines for red 657nm, blue-green 486nm...

I have been getting rather confused with rest mass, m0. here's the problem. A particle intially has a speed of 0.58c. A) At what speed does it momentum increase by 1%. B) At 10%, and C) At 100%. I have set it up as p=γm0v... then γ=1/ sqrt[1=(0.58)^2 but don't know what to do any...
