Q1. The potential energy of two atoms in the diatomic molecule is approximated by, where is the spacing between atoms and is positive constants. Assume the distance between the two atoms is equal to equilibrium distance found in part A. What minimum energy should be added to the molecule to dissociate it-that is, to separate the two atoms to an infinite distance apart? This is known as the dissociation energy of the molecule.
Express your answer in terms of the variables a and b.
Q2. Light from the sun is incident on the surface of a pond with a smooth surface. The light strikes the surface at the angle of 30 to the surface and is partially reflected. What is the angle of reflection for the reflected portion? What is an angle of refraction for the transmitted portion? Note down that the index of refraction of water is 1.43.
What is an angle (theta a) of incidence?
