| Abstract: | The traditional experiment of measuring laser wavelength with biprism is improved.The sodium lamp is substituted by He-Ne laser,the slit is removed,a screen or wall is substituted for the traveling microscope and the distance between the two virtual light sources is measured by the first imaging method.The improved device can be operated easily and the phenomena is obvious. |
