Question

Light of wavelength 550 nm passes through a double slit, yielding a diffraction pattern whose graph of intensity I versus angular position θ is shown in the figure. Calculate the slit width (in m).

- I plan to use the equations asin(theta) = (m)(lambda) and I_diffraction = I_max[sin(((pi)(a)(sin(theta)))/lambda)/((pi)(a)(sin(theta))/lambda)]^2

Can someone please guide me which possible values I can plug in to those equations? ...if they are even the appropriate ones to use to solve.

Answer 2

Thank you, and I would just like to know how you are able to post links, since this site always says that I am unable to.

I can answer that last question for you. The tutors here are allowed to post links by the web master. Only the tutors who have been cleared can do that.
