In an experiment of single slit diffraction pattern, first minimum for red light coincides with first maximum of some other wavelength. If wavelength of red light is 6600 Å , then wavelength of first maximum will be:
Options
- A3300 Å
- B4400 Å
- C5500 Å
- D6600 Å
Correct answer
B. 4400 Å
Step-by-step solution
In a single slit experiment, For diffraction maxima, a = (2 n+1 Å 2 . and for diffraction minima, a = n According to question, aligned & (2 1+1 2 =1 6600 . & ( _ R =6600 Å ) & = 6600 2 3 & =4400 Å aligned
