Document Summary

Nb: mark values are given in brackets [ ] beside each problem. Write all your answers on the quiz paper. Wave function: y = a sin(kx t + ) where k = 2 / . Two-slit interference: sin = m /d and sin = (m+1/2) /d. Two wave pulses pass each other on a string. One is traveling to the right with a positive amplitude, while the other is traveling to the left with a negative amplitude. The magnitudes of their amplitudes are the same. A single-slit di raction pattern is formed on a distant screen. Assuming that the angles involved are small, by what factor will the width of the central bright spot on the screen change, if the slit width is doubled: [2+2+2] In a young"s double-slit experiment, the slit separation is made to be exactly 4 , where is the wavelength of the light used in the experiment.
