Lecture 31 Outline of Last Lecture I. Single Slit Diffraction a. Wsinθ = mλ b. λ/W: ratio determining the amount of diffraction coming from a slit; larger number means more diffraction (bending of light) II. Resolving Power (Resolution) a. sinθmin = 1.22 (λ/d) Outline of Current Lecture III. Particle Wave Duality a. Particles can behave like waves and exhibit interference effects. i. Electrons and other particles can exhibit wave-like properties. IV. Black Body Radiation a. Black body: an ideal system that absorbs all radiation incident on it, thus appearing black i. Common model: hollow spherical container with small opening, increases temperature as it absorbs radiation b. For black body radiation, there is a characteristic distribution of wavelengths, dependent on the temperature of the object. c. Wien’s Law: λmaxT = 2.898 x 10-3 i. As T increases, λmax decreases.
