Individual slit width:
Slit separation:
Wavelength of light:
In the double slit experiment, there will be interference due to difference in the phase of two paths and diffraction (bending of light) in the single slit.
Now, the first minima will be given as:
Now, the angular locations due to interference is:
From equation,
Substituting the known values and solving,
Therefore, there are 5 complete bright fringes in each side along with the central maximum. Hence, the number of complete bright fringes appearing between the two, first order minima of the diffraction pattern is 11.
Answer is 11 (no units).

A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?
