Embodiment Construction

[0015] The present invention will be further elaborated below in combination with specific embodiments.

[0016] Such as figure 1 Shown: a demonstration device for the propagation path of light in a medium with a constant gradient of refraction, the device is provided with two rectangular or square smooth flat plates 1, the smooth flat plates 1 are transparent plastic plates, two light The angle between the surface plates 1 is less than 90 degrees, and the smooth plate 1 at the bottom is horizontal, and the two smooth plates 1 are connected and fixed by two plastic connecting columns 2 with unequal lengths, and the two connecting columns 2 are It is perpendicular to the horizontal flat panel 1 .

[0017] Such as figure 1 As shown, the included angle between the planes where the two transparent plastic sheets are located is α. Immerse the device in soapy water and then take it out. At this point, a soap film will form between the two connecting posts. The intersection line ...

Abstract

The invention relates to a demonstration device for a propagation path of light in a medium with a constant serving as a refractive gradient. The device comprises two glossy flat plates, the includedangle between the two glossy flat plates is smaller than 90 degrees, the bottom glossy flat plate is horizontal, the two glossy flat plates are fixedly connected through two connecting columns, and the two connecting columns are perpendicular to the horizontal glossy flat plate. The device is soaked into soapy water and then taken out, a soap film is formed between the two connecting columns, andthe intersecting line of the soap film and the bottom horizontal glossy flat plate is the propagation path of the light in the medium with the constant serving as the refractive gradient. The device can visually demonstrate the propagation path of the light in the medium with the constant serving as the refractive gradient, and is simple in structure, convenient and practical.

Description

technical field [0001] The invention relates to the technical field of light propagation path demonstration, in particular to a demonstration device for light propagation path in a medium with a constant refraction gradient. Background technique [0002] In study and life, people's various perceptions often come from life experience, and they have no specific sense of image for boring values, and some theories are too abstract and out of touch with life. For example, the propagation path of light in a medium with a constant gradient of refraction, when learning related knowledge, the perception of direction, speed, space, and time is purely mathematical, and people often have no practice and experience in their lives, so although they know and understand This law has no impact on life. The relationship between the elements described in its principle is sufficient for our perception of direction, speed, and space theory. How can we use this law to promote and strengthen our u...
