Question1

The pattern if intensity I versus position x (shown below) is measured on a wall 20 meters from a set of N identical, parallel slits. Light of wavelength λ = 6000 A passes during the slits, each of which has width b, and which are spaced from each other by a distance d. What are the values of N, b and d? Give a reason for each respond.

Question2

A 5.25-kg ball hangs from the top of a vertical pole by a 2.47-m-long string. The ball is struck, causing it to circle around the pole at a speed of 4.15 m/s in a horizontal circle with the string remaining taut. Create the angle, between 0° and 90° that string makes with the pole. Take g = 9.81 m/s2.and what tension in the string is?
