Question
When 450-nm light is incident normally on a certain double-slit system the number of interference maxima within the central diffraction maximum is 5. When 900-nm light is incident on the same slit system the number is: ______ The answer is 5. How do you get this?When 450-nm light is incident normally on a certain double-slit system the number of interference maxima within the central diffraction maximum is 5.

When 450-nm light is incident normally on a certain double-slit system the number of interference maxima within the central diffraction maximum is 5. When 900-nm light is incident on the same slit
Explanation / Answer
double-slit system the number of interference maxima within the central diffraction maximum is independent of wavelegth.hence we will get 5 only
