Question

This calculation depends on the angle ? being small because the small angle approximation was implicitly used. The measurement of the position of the bright fringes yields the wavelength of light, which in turn is a signature of atomic processes, as is discussed in the chapters on modern physics. This kind of measurement therefore helped open the world of the atom.

Which of the following make the separation between fringes greater in the two slit interference experiment? (Select all that apply.)

A. Smaller separation of the two slits.
B. Wider slits.
C. Narrower slits.
D.Larger separation of the two slits.

Please help
