53791 repetitive arrays of diffracting elements are uniformly
spaced over 42mm. This grating is illuminated at normal
by yellow sodium vapor lamp which has a
frequency 5.09⋅10145.09·1014 Hz. Assume that the light
travels in vacuum.
Which formula can be used to calculate the location of a
bright fringe on the viewing screen? (refer to the formula sheet
and select the number of the correct formula from the list)
At what angle will the third order maximum occur? Find
your answer in degree (do not use the small angle
approximation).
