This graph represents an exothermic reaction. What does it show about the potential energy of reactants and products?
Potential energy
n
Reaction progress
A. The comparison of potential energy depends on what the
reactants and products are.
B. The potential energy of the reactants equals the potential energy
of the products.
C. The potential energy of the products is greater than the potential
energy of the reactants.

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
