ABG Question 23
Jason holds a stick partway in a pond. When he looked down at the stick, it appeared to be broken at the point where
the stick entered the water. This experience is best explained by
А
the absorbtion of light waves by the stick.
B
the refraction of light waves passing from the air into the water.
с
the diffraction of light waves around the stick.
D
the reflection of light waves from the water.

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.
