Determine the speed, wavelength, and frequency of light from a helium-neon laser as it travels through sodium chloride. The wavelength of the light from the laser is 632.8 nm in air and the index of refraction of sodium chloride is 1.544.

Because its reliable.   there is no pollution  the chances of a radiation leak is low

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.
