Problems solved by technology

This method is simple to operate and the principle is clear. However, in actual teaching, it is not intuitive, not vivid, and it is not easy to make a deep impression on the observer, and the scope of observation of the observer is limited, only limited to observing the underwater environment above the water. The refraction phenomenon of objects, the refraction phenomenon of objects on the water surface cannot be observed underwater, the contrast is not obvious

Embodiment 1

[0014] Embodiment 1: This embodiment describes the structure and composition of the refraction contrast demonstration instrument of the present invention:

[0015] Such as Figures 1 to 3 As shown, the present embodiment is composed of a bottom box 3 and a container 1, wherein the bottom box 3 is provided with observation holes 6, 11 and a slope 4, the slope 4 is provided with a reflective lens 5, and the reflective lens 5 can be bonded on the slope 4 , and other fixing methods can also be used. The position of the reflective lens 5 matches the positions of the observation holes 6 and 11. The observer can observe the observed object through the reflective lens 5 from the observation holes 6 and 11. The middle of the container 1 is set A partition 7 is arranged, and the partition 7 divides the container 1 into two parts, the left chamber 8 and the right chamber 9, which are not communicated with each other.

Embodiment 2

[0017] This embodiment describes the method for observing objects above the water surface under the water surface of the present invention:

[0018] Such as Figure 4 As shown, the observed object 2 is placed above the water surface. When no water is injected into the left cavity 8 and the right cavity 9, the observed object 2 is observed from the observation hole 6 and the observation hole 11 respectively. It can be found that from the observation The height of the observed object 2 observed by the hole 6 and the observation hole 11 is consistent; then about one-third of the water is injected into the left cavity 8. At this time, observing the observed object 2 from the observation hole 6 is equivalent to that at the bottom of the water. Observing the object on the water surface and then observing the observed object 2 from the observation hole 11 is equivalent to observing from bottom to top in the air. At this time, it can be found that the scene observed in the observation...

Abstract

It is an infraction comparison demo device and its method, which comprises container and bottom box, wherein the bottom box is set on the bottom of the container. The two bottoms of the container are separately set with slopes with reflector and an observation holes on the matching place between the bottom reflector lenses. We can observe the object refraction changes on the water surface through the observation holes and reflection lens.

Description

technical field [0001] The invention relates to a teaching instrument and a demonstration method thereof, in particular to a refraction contrast demonstration instrument and a demonstration method thereof. Background technique [0002] In teaching practice, in the teaching of demonstrating the refraction phenomenon of light to observers, the existing method is: put an object into a container filled with water, and through observation above the water, the object finds that the imaging position is high Based on the actual position of the object, the specific value of refraction is obtained through calculation. This method is simple to operate and the principle is clear. However, in actual teaching, it is not intuitive, not vivid, and it is not easy to make a deep impression on the observer, and the scope of observation of the observer is limited, only limited to observing the underwater environment above the water. The refraction phenomenon of objects, the refraction phenomen...
