光は回析や干渉といった波動特有の現象を示すが、波動性では説明できない現象も示す。例えば、光を金属に照射すると、金属内の電子が光を吸収して金属から飛び出すことがある。この現象は光電効果といわれ、光を光子という粒子の集まりと考えないと説明できない、光電効果の原理は明快で初等物理学程度の知識で理解できるので、教養課程の物理学実験テーマとして多数の大学で採用されてきた。今回、物理学実験に光電効果の実験を導入するため、検討を行った。

[概要] 量子なる概念は, プランクの放射公式によって議論に俎上した. しかし, それは未だ単なる関数的関係にすぎず, リアルで現実的な物理的実体ではなかった. プランクの量子は現実存在ではないのである. これに対してアインシュタインは, 光量子仮説を導入することで, 量子をリアルでビビッドな存在とし, 量子は実体となった. これは, 量子を粒子として実体化することでもあった. われわれは, 本論において, このアインシュタインのアイデアと実体化の過程を詳細に追跡し, 幾ばくかの哲学的側面についての考察も行う. また, 考察の過程で波動一粒子の二重性の根源についての議論も行うこととなる. [Abstract] The concept of quantum came up in the discussions by the Planck's formula for radiation. However, it was a merely a functional relation, but not physical substance that is the reality. Planck's quantum does not have a real existence at all. In contrast with this, Einstein proposed the hypothesis of the light quanta as a real and with a vivid existence. Thus the quantum becomes a physical substance. This is also a substantiation of quantum as particles. We will see the process of this substantiation and the developments of the Einstein's idea in this article in details and have a few philosophical discussions about this process. We will see and also argue about the roots of the wave-particle duality.

application/pdf, 論文(Article), Solar energy is clean and inexhaustible. Therefore an increase in solar power system in demand is estimated. To study about the solar power system, an actinometer is used for measuring ray of light incidence. The characteristic of an actinometer is expected that the spectrum is flat in wide range of the wave length of incident light. But it is very expensive. We want to find more inexpensive measureing method of solar energy to be used for the terrestrial solar power system with the silicon solar cells. By combining two or three photodiodes, which have different characteristics in the spectram, we mesured the solar energy. The short circuit current was measured in the parallel circuits. And the informations were fed to the data-logger. The result of measured value of solar energy by the combining of photodiodes agree with the measured value by ordinary thermal senser type actinometer.
