Q. A single slit has a width of 2.1x10^(-6)m and is used to form a diffraction pattern. Find the angle that locates the second second dark fringe when the wavelength of the light is 430 nm.

Q. A simple pendulum, 1.0 m in length is released from rest when thesupport string is at an angle of 35 degrees from the vertical. What is the speed of the suspended mass at the bottom of the swing. (no air resistance, g = 9.8 m/s2)
