The invention relates to the field of
physics teaching equipment, and belongs to an optical phenomenon display instrument. The propagation path of light and generated
optical phenomena can be displayed clearly. The instrument comprises a rotatable base, and a magnetic disk with length and angle scales. One fourth of the upper half part of the disk can be turned backwards, one side of the
lower half part is equipped with a semicircular glass
brick, and the other side of the
lower half part is equipped with a semicircular water tank which can be filled with different transparent liquids. The instrument further comprises the following attachments: a magnetic lamp holder, a modified electronic
laser lamp, an electronic
candle, a pinhole imaging plate capable of adjusting the size of a pinhole, a magnetic clamping slot, a
plane mirror imaging transparent
glass sheet, a single-slit and double-slit
diffraction interference lens, a reflection
diffraction grating, a polarization
glass sheet, a convex lens with a magnetic base, a concave lens, a
prism, an optical screen, and the like. All the attachments can be placed on the magnetic disk, and 18 groups of different optical experiments can be completed by choosing different attachments.
