For the ideal case double slit interference, maxima occur at d sin(θ) = mλ, where: d is the distance between the centers of the slits theta is the angle from the line between the slits m=0,1,2,3,... lambda is … The calculator will find the angle (in radians and degrees) between the two vectors, and will show the work. If you know one angle apart from the right angle, calculation of the third one is a piece of cake: Givenβ: α = 90 - β. Givenα: β = 90 - α. Look up the wavelength of the color you chose. Reinforcement occurs when the path lengths to the screen from the two slits differ by mλ (an integer number of wavelengths). Because the spacing between the slits is generally very small, the angles θ are generally quite large. d multi-slit interference Diffraction grating dsinθ=mλ m=0 m=1 m=2 m=-1 m=-2 m=0 m=1 m=2 m=-1 m=-2 λ Higher intensity Question A grating in a spectrometer has a length of 2 cm and has contains 104 lines.
