Light of wavelength 645 nm is incident on a double slit. The angle between the central bright fringe and the second dark fringe
is 4.90°. Determine the separation d of the slits.
1 answer:
Answer:
Slit separation,
Explanation:
It is given that,
Wavelength of light,
The angle between the central bright fringe and the second dark fringe,
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is . Hence, this is the required solution.
