If there exists a phenomenon in which a certain physical quantity takes the value a ( t ) at time t , and another phenomenon in which it takes the value b ( t ), and if there also exists a phenomenon whose value is the sum λa ( t ) + μb ( t ) obtained by multiplying these quantities by arbitrary coefficients λ and μ and adding them together, then the principle of superposition is said to hold for these phenomena. Solutions to linear equations follow this principle. For example, this principle holds for light waves. Therefore, if light from a light source P is incident on a point on a screen, [Hiroshi Ezawa] "Mechanics by Hiroshi Ezawa (2005, Nippon Hyoronsha)" [Reference] | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
ある物理量が時刻tにa(t)という値をとる現象があり、またb(t)という値をとる現象があるとき、それぞれに任意の係数λ、μを掛けて加えた和λa(t)+μb(t)を値とする現象も存在するなら、これらの現象に対して重ね合せの原理が成り立つという。線形な方程式の解は、この原理に従う。たとえば、光の波に対しては、この原理が成り立つ。それゆえ、光源Pからの光がスクリーン上の1点で [江沢 洋] 『江沢洋著『力学』(2005・日本評論社)』 [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
