Late one night on a highway, a car speeds by you and fades into the distance. Under these conditions the pupils of your eyes have diameters of about 7.0 mm. The taillights of this car are separated by a distance of 1.2 m and emit red light (wavelength 660 nm in vacuum). How far away from you is this car when its taillights appear to merge into a single spot of light because of the effects of diffraction?
Chapter 1: Interactions and Motion ● Kinds of matter (four fundamental interactions in nature) ○ Gravitational on the cosmic scale ○ Electromagnetic, strong and weak nuclear force in the scale of atoms ● Gravitational interactions between objects (weakest) ● Electromagnetic between electric charges (2nd strongest) ● Strong nuclear interactions between subatomic particles; HOLDS nucleus together/acts over short distance (strongest) ● Weak nuclear interactions that arise in certain radioactive decay process (alpha, beta); acts over short distances (3rd strongest) Scales and Vectors ● All physical qualitie
