Atomic models have changed over the decades. Two early atomic models can be seen here. There is a dramatic change in the models, as Rutherford experimented with the cathode ray tube and charged particles. Differentiate between the two models by selecting the main difference between the models. Question 5 options:

Rutherford's model shows negative charges dispersed throughout the atom

Rutherford's model shows negative particles orbiting the central nucleus

Rutherford's model shows the positive charge of an atom as a very small area

Thomson's model shows at sea of negative charged particles surrounding a small, positive area

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.
