Extensively, either all of crucial importance in the communications field or lighting area.Study the property using light, it is necessary to grasp light
Fundamental property, wherein the reflection of light and law of refraction are a property the most basic.Light is slanted through another from a kind of medium
When kind medium, the direction of propagation changes, to make light that deviation occur in the intersection of different medium.The teaching imparted knowledge to students now
There is no a kind of easy experimental provision in practice, student is allow to observe reflection and the law of refraction of light by shirtsleeve operation.
Utility model content
For the deficiency in above-mentioned background technique, the utility model proposes a kind of refraction experiment devices of light, solve object
The technical issues of reason Students in Teaching can not intuitively observe refraction, the reflexive property of light by simple experimental implementation.
The technical solution of the utility model is achieved in that a kind of refraction experiment device of light, including non-covered container, nothing
Being horizontally arranged on the bottom wall of lid container has one piece of reflective mirror, and the mirror surface of reflective mirror is upward, and the top of the right side wall of non-covered container is set
It is equipped with laser lamp, the ejecting end of laser lamp is arranged diagonally downward and towards the bottom wall of non-covered container, and laser lamp passes through with switch
Conducting wire be connected with power supply.
The height of the left side wall of the non-covered container is higher than the height of right side wall, is provided with a column height on the inside of left side wall
Scale.
The horizontal concrete chute perpendicular with right side wall, the reflective mirror activity clamping are offered on the bottom wall of the non-covered container
In horizontal concrete chute.
The end of the reflective mirror is connected with catch bar.
A column position scale, moving direction of the position scale along reflective mirror are provided on the bottom wall of the non-covered container
Setting.
It is provided with a column liquid on the wall surface of the non-covered container and shows high line.
The utility model can directly be projected on the left side wall of non-covered container by the laser lamp and reflective mirror of setting
Reflected image；Then gradually reflective mirror is moved in the direction of side wall to the right, when the injection light of laser lamp can not be thrown on reflective mirror
When, it can't see reflected image on left side wall；Then liquid is injected into non-covered container, when water is injected into certain depth, can be weighed
The image that laser lamp issues newly is seen on left side wall.By this process, the reflexive property and refraction effect of light can be learnt,
The transmission path of light can shift when reaching between another medium from a kind of medium.Horizontal concrete chute is set, can be made anti-
Light microscopic is reliable and stable when position is mobile；Catch bar is set, convenient for easily pushing the position of reflective mirror, while being also avoided straight
Connect the contamination phenomenon caused by the mobile reflective mirror of hand.Setting altitude scale, liquid, which show high line and position is arranged on bottom wall, to be carved
Degree can accurately determine the shift position of reflective mirror surely, be accurately positioned to use different liquids to observe refraction effect, in turn
Compare the refractive index size of different liquids.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs 1-4, embodiment 1, a kind of refraction experiment device of light, including non-covered container 1, a left side for non-covered container 1
Side wall 2 is higher than the height of right side wall 3, front side wall 4 and rear wall 5, and the inside of left side wall 2 is provided with a column altitude scale, height
Scale can indicate refracted light and the final launching position of reflection light.It is offered on the bottom wall 6 of non-covered container 1 and right side wall
5 perpendicular horizontal concrete chutes 601, sliding is placed with reflective mirror 602 in horizontal concrete chute 601, the mirror surface of reflective mirror 602 upward, instead
Light microscopic 602 can horizontally slip in horizontal concrete chute 601.
The top of the right side wall 3 of non-covered container 1 is provided with laser lamp 7, and the ejecting end of laser lamp 7 is arranged diagonally downward and court
To bottom wall 6, laser lamp 7 passes through the conducting wire with switch and is connected with power supply 8.After turning on the switch, laser lamp 7 is projected light beams upon the bottom of to
