The absorption spectrum of an atom consists of the wavelengths 200 nm, 300 nm, and 500 nm. What wavelengths are seen in the atom's emission spectrum? To answer this question, first draw the atom's energy-level diagram and label the quantum states n = 1, 2, 3, and so on. Lambda 41, 31, 21, 43
Answer the four in nm
A 5 g bullet with speed of 400m/s gets stuck in a 1 kg wooden block (originally not moving). Classify the collision. (b) Find the new speed of block+bullet. (c) Find the amount of kinetic energy lost. Where does it go?
