ここで、$ v_a $ $ v_b $はそれぞれ物質の中での波の速度を示し、$ \frac { v_a }{ v_b } $ を屈折率(refraction index)とも呼びます 少し変形してやれば、 \frac { \sin { \theta _{ a } } }{ \sin { \theta _{ b } } } =\frac { v_{ a } }{ v_{ b } } \\ \sin { \theta _{ a } } =\frac { v_{ a } }{ v_{ b } } \sin { \theta _{ b } } \\ \frac { v_{ b } }{ v_{ a } } \sin { \theta _{ a } } =\sin { \theta _{ b } } \\ \theta _{ b }=\arcsin { \frac { v_{ b } }{ v_{
It’s always good to be able to articulate design choices to your clients; why you put something where, why you chose the color scheme you did, etc. This knowledge is one of the biggest differences between a designer and a non-designer.
