Find the separation between the slits.
Answer to Problem 36P
The separation between the slits is
Explanation of Solution
The schematic diagram of the slit and the interference process is shown in figure 1 below.
The angle of interference of both red and violet lights is very small. So
Write the equation to find the
Here,
Write the equation to find the wavelength of violet light.
Here,
Write the equation to find the angle of interference.
Divide equations (I) and (II) and find
Write the equation to find the difference of
Rewrite equation (V) to get
Multiply equation (VI) by
Conclusion
Substitute
Therefore, the separation between the slits is
