The wavelength of the laser light is 576 nm, and the screen is 1.69 m away from the wire. What is the diameter of the wire? (Hint: one of the higher order diffraction minima lines up with a well defined x-value. Also, it is perfectly safe to use the small angle approximation: sin(θ) = tan(θ)).

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive
