onstitutes what, in optics, is known as the focus ;after passing the focus the wave spreads out again spherically RESONANCE 157 (5, 6,7, 8). The end portions of the reflected wave, which areprominent in Nos. 6, 7, 8, are introduced to illustrate thephenomenon of spherical aberration (vid. inf. p.… … Fig. 54. turbance is reflected, but the greater portion travels onward andsuffers refraction; this is clearly seen in Nos. 1, 2, where therefracted portion is seen to have travelled a less distance thanthe reflected. In No. 4 the wave has struck the bottom of thevessel of carbon dioxide and is…
