PROBLEM TO BE SOLVED: To perform excellent recording/reproducing and to prevent also a margin for a tilt and defocus from being damaged by constituting the numerical aperture NA of the objective lens of the optical path of the outward path from a semiconductor laser to an optical disk larger ...
which we can see because our screen emits visible light. 我们可以看见这些是由于屏幕发出可见光。 Nuclear radiation, on the other hand, 另一边呢, originates in the atomic nucleus, 核辐射源于原子核, where protons repel each other due to their mutually positive charges. 带有正电荷的质子正正相斥。

根据第二段第三句The human eye is sensitive to a form of electromagnetic radiation that lies in the wavelength range between 400 and 700 nanometers(纳米), commonly known as the visible light spectrum, which is the only source of color.可知,可见光是颜色的唯一来源,而可见光又属于电磁辐射,由此...

would produce a photocurrent in the metal, whereas longer wavelength (red) light—even at high intensity—would not produce a photocurrent. This curious observation strongly supported the quantum theory of radiation. Some German physicists theorized that a single photon (particle of light) has a ...
