WebNov 8, 2024 · It is for this reason that diffraction gratings are generally characterized by their grating density – the number of slits per unit distance. Of course such a number … WebOrders of Maxima. The maximum angle to see orders of maxima is when the beam is at right angles to the diffraction grating. This means θ = 90 o and sin θ = 1. The highest order of maxima visible is therefore calculated by the equation: Note that since n must be an integer, if the value is a decimal it must be rounded down. glastonbury met office weather https://sptcpa.com
