atio is constant ; that is, if thesine of incidence becomes twice or three times as large, the sine of refractionincreases in the same ratio, which demonstrates the first law. The secondlaw follows froni the arrangement of the apparatus, for the plane of thegraduated limb is perpendicular to the… … Fig- 515 554 On Light [547- second medium with respect to the first. Thus if ;/ is the refractive index,and i and r the angles of incidence and refraction, sin / = « sin r. The refrac-tive index varies with the media ; for example, from air to water it is |, andfrom air to glass it is \. When the…
