b.) d.) What difference if any does increasing the screen distance x have on the hinge pattern spacing y? y ~ x y ~ 1/x 31 does not depend on x Based on your conclusion, reducing the screen distance will cause the pattern to contract (decrease y). expand (increase y). remain the same. Decrease the slit-to-screen distance by moving the barrier towards the screen. Move the barrier so that the distance between the screen and barrier is around 1500 nm. This means that the measured x is 1500 nm. You may want to reduce the amplitude to better dene the fringes. Use the tape measure to make sure you place the barrier at this position. Record positon. x = . Use the tape measure to measure the resulting minimum-to-minimum distance. Record your observations. Record distance. y = . Return the barrier to a distance of 25 00 nm from the screen. Use the tap measure to measure the distance between the barrier and the screen. Record position. x = This places it half way between the light source and the screen. Also make sure that the amplitude is set to the maximum value
