Question Video: Identifying the Equation for the Dispersive Power of a Prism Physics
Which of the following formulas correctly relates π_(πΌ), the dispersive power of a prism, to π_(min), the refractive index of the prism for the shortest wavelength of light that passes through it, and π_(max), the refractive index of the prism for the longest wavelength of light that passes through it? [A] π_(πΌ) = (π_(min) + π_(max))/(((π_(min) β π_(max))/2) β 1) [B] π_(πΌ) = (π_(min) + π_(max))/(((π_(min) β π_(max))/2) + 1) [C] π_(πΌ) = (π_(max) β π_(min))/(((π_(max) + π_(min))/2) β 1) [D] π_(πΌ) = (π_(min) β π_(max))/(((π_(min) + π_(max))/2) + 1) [E] π_(πΌ) = (π_(min) β π_(max))/(((π_(min) β π_(max))/2) β 1)
