In a Young's double-slit experiment, the slit separation dis made twice as big(doubled) but the fringe pattern observed on the screen does not change. Which ofthe following changes would keep the pattern identical when dis doubled?Use a wavelength of light that is half as big but keep the distance from the slitsto the screen constant.Use a frequency of light that is twice as big but keep the distance from the slitsto the screen constant.Change the distance from the slits to the screen to be half of what it wasoriginally but keep the wavelength of light the same.More than one of the above would work.O None of the above.

While doing some spring cleaning you find an old laser pointer. Youtake the laser into your physics laboratory to perform a double-slitexperiment. The distance from the barrier to the screen is 2.50 m andthe two slits are 0.350 mm apart from each other. You measure thedistance from the central maximum to the 2nd order maximum andfind that it is 9.04 mm. What is the wavelength of your laser pointer’slight?
