Consider an experiment using a diffraction grating with 7000 lines/cm, a screen 2.50 m away, and a 440-nm wavelength beam of light. a) how many side maxima will be observed on one side of the central maximum? (hint: the largest m when q = 90°)
b) what is the angle formed by the first-order bright spot and the central maximum?
c) how far apart on the screen are the first-order and second-order maxima on the same side of the central maximum?

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.  

ingenuity says that the answer is 2.7 m.
