At what angle in degrees is the first-order maximum for 460-nm wavelength blue light falling on double slits separated by 0.0500 mm?

The angle is

Explanation:

From the question we are told that

    The number of order is  n =  1

     The wavelength is  

     The separation between the slit is  

Generally the condition for constructive interference is  

=>    

=>    

=>    

=>    

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
