Question
Answer
a. the screen is far away b. the slit width is greater than a wavelength c. the slit width is less than a wavelength d. the wavelength is less than the distance to the screen e. none of the above (fringes are always seen)Which one of the following mathematical expressions is correct for destructive interference for two beams of light in the double slit experiment? Answer a. Path Difference = (m + 1/2)*lambda, m = 0, 1, 2, . . . b. Path Difference = lambda /m, m = 0, 1, 2, . . . c. Path Difference = m* lambda, m = 0, 1, 2, . . . d. Path Difference = m/ lambda, m = 0, 1, 2,. . . . e. Path Difference = (m + 3/2)*lambda, m = 0, 1, 2,. . . .
