Answer: i dont understand the question
Explanation:
Intensity is the word you are looking for!
Snell's law is generally true only when:
1) the beam of light is monochromatic (of one single wavelength, as for example laser beams)
2) the media through which the light beam travels must be isotropic (uniform in all directions, as for example glass)
In these conditions:
sin (r) / sin (i) = n₁ / n₂ = λ₂ / <span>λ</span>₁
