The diagram shows light passing through an opening and forming bands.

there is an incident beam of light toward an opening in a grating. the light breaks into 7 different paths labeled n = 3, n = 2, n = 1, n = 0, n = 1, n = 2 and n = 3.
which two order bands are the dimmest?

n = 0 and n = 1
n = 0 and n = 3
n = 1 and n = 2
n = 2 and n = 3

The answer is 12, for the points

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
