Answer:
5 orders.
Explanation:
The condition for diffraction maxima,


So maximum m is 5 which means it produce 5 orders.

Answer:
Buoyant Force: Cause and Calculation
The result is a net upward force (a buoyant force) on any object in any fluid. If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink.
