Objective: Determine the focal length of a lens using the Bessel method On an optical bench it is possible to set up a light source, a lens, a screen and an object to be imaged in such a way that a well focussed image appears on the screen ... 更多

Objective: Record and interpret transmission spectra of transparent bodies A digital spectrophotometer is used to measure transmission spectra. In this instrument the transmitted light collected by an optical fibre is separated into its ... 更多

Objective: Demonstrate the wave nature of light and determine the wavelength Diffraction of light by a single slit can be described as the superposition of coherent wavelets which, according to Huygens’ principle, spread out from the ... 更多

Objective: Demonstrate the wave nature of light and determine the wavelength. The diffraction of light by multiple slits or a grating can be described by considering how the individual components of the coherent wave radiation are superimposed ... 更多

Objective: Generating interference between two beams using a Fresnel biprism. Refraction of a divergent light beam by means of a biprism separates the beam into two parts which, since they are coherent, will interfere with one another. The ... 更多

目标 演示并探究迈克尔逊干涉仪的工作原理   在迈克尔逊干涉仪中，通过在光路中插入半银镜，将相干光束分成两束不同方向的光线。分开的光束沿自身方向反射回来，然后重新组合。当每束分离光的光路长度按光波长的几分之一变化时，观察屏就会显示出明显变化的干涉图案。 更多

目的：测定玻璃的折射率 迈克尔逊干涉仪可用于干涉测量的折射率，特别是因为它是敏感的光路的变化的分裂光束。如果几何路径保持不变，那么折射率或折射率的变化，可以从压力，温度或密度的变化来确定。一个轻微的修改改变了迈克尔逊干涉仪为泰曼-格林干涉仪，使光学仪器表面的质量来衡量的。在实验中，玻璃的折射率是通过以下方式获得的路径差异的光通过玻璃块旋转到不同角度作为一个功能的角度。通过构造性或破坏性干涉产生的计数环建立路径差。此外，胶粘带的表面质量可以从由胶带表面不均匀引起的干涉环 ... 更多

Objective: Demonstration of “quantum erasure” in an experiment by analogy Light itself can be described in quantum mechanics by means of wave equations. From this it is possible to derive the spatial distribution of the probability ... 更多

Objective: Investigate the rotation of the plane of polarisation by sugar solutions Sugar solutions are optically active, in other words they rotate the plane of polarisation of any linearly polarised light that is passed through them. The ... 更多

Objective: Demonstration of Pockels effect in a conoscopic beam path The Pockels effect is an electro-optical effect in which an electric field within a suitable material splits a light beam into two beams polarised perpendicular to one ... 更多

Objective: Demonstrate the Faraday effect and determine the Verdet constant for flint glass Optically isotropic, transparent, non-magnetic materials become optically active in a magnetic field. They rotate the plane of polarisation of linearly ... 更多

Objective: Verify the inverse square law for the intensity of radiation from a source of light According to the inverse square law, the intensity of radiation from a light source, i.e. the power per unit area, is inversely proportional to ... 更多

Objective: Verify that intensity of radiation is proportional to the fourth power of the temperature, T4 The way that intensity of radiation from a black body depends on temperature is described by the Stefan-Boltzmann law. Similar ... 更多

Objective: Determine the velocity of light from the transit time of short light pulses The fact that light is propagated at a finite speed can be demonstrated by a simple transit time measurement. This is achieved by using very short light ... 更多
