Q. A 302g ball is tied to a string. It is pulled to an angle of 6.00 degrees and released to swing as a pendulum. A student with a stopwatch finds that 17 oscillations take 12.0s. How long is the string?

Q. A new experiment is created with the screen at a distance of 2 m from the slits (with spacing 0.08 mm). What is the distance between the second order bright fringe of light with l = 690 nm and the third order bright fringe of light with l = 404 nm? (Give the absolute value of the smallest possible distance between these two fringes: the distance between bright fringes on the same side of the central bright fringe.)
