#1 Interference phenomena
Coherent light strikes a two slit arrangement, and alternating bright and dark fringes are produced on a screen far from the slits. The bright fringes are due to the fact that
A. The path lengths of rays coming from the slits differ by half a wavelength.
B. The path lengths of rays coming from the slits differ by an integer number of wavelength.
q, C. The path lengths of rays coming from the slits differ by one and a half wavelengths.
D. The path lengths of rays coming from the slits differ by two and a half wavelenghts.#1 Interference phenomena
