빛 가상실험실2

Virtual experiments and learning related to straightness, refraction, refraction, dispersion, and synthesis of light can be done.

It can be used for classroom related to light in elementary and junior high school science hours.

1. Straight Light

 - Shadow Experiment: After experimenting with the real light source to see why the size of the shadow is getting closer to the light source and why it gets smaller when it gets farther away, the virtual path of the light is shown as a line in the virtual experiment. I can more easily understand why it happened

 - Needle-hole camera experiment: Even in the case of a needle-piercing camera, it is difficult to understand only the reason that the image is inverted on the needle-hole camera made by students. It is difficult to understand the path of the light originating from the head of the rabbit, So you can easily understand why you are upset

2. Reflection of light

 - Light Reflection Experiment: It is difficult to see the path of light reflected on the actual mirror in the experiment of light reflection and it is difficult to measure the angle, but it is easy to see the path of light by using virtual experiment, Can easily understand the law of reflection

 - Mirror Experiment: It is easy to see why the image seen in the mirror changes to the right and left, and how to perform the levitation play in the mirror

3. Refraction of Light

 - Light refraction experiment: I can see the path of the invisible light, and I can easily understand the refraction by observing the refracting path in the diamond which I can not actually do.

 - Lens Construction Experiment: In case of convex lens construction experiment, it is possible to predict where the lens and object will be placed in some place by using virtual experiment application when performing an experiment in which an image is generated according to the position of an object. Experiments can be performed in comparison with experiments

4. Dispersion of light

 - Prism experiment: You can see how the light passing through the prism is divided, and what happens if there is no prism. And you can easily understand the principle of dispersion of light by observing which colors are breaking more

5. Synthesis of light

 - Experiment of light synthesis: It is possible to understand what kind of color comes out by combining the three primary colors of light.

1. Press the MENU key to go to the main screen at any time.

2. Press the back key to exit from any screen and exit.

3. You can perform the desired virtual experiment by pressing the desired item button on the main screen.

4. On the virtual experiment screen, you can select or deselect the desired condition by placing a selection button at the bottom in common.

5. In experiments where gravity sensors can be used, the G sensor button is placed at the upper left corner to allow the experiment to be performed with the slope of the smartphone, and the gravity sensor can be deselected if not used.

6. If you have to select and drag with your finger in a virtual experiment, you can easily start by starting a virtual experiment or selecting the G sensor button by blinking the red circle on the object to be manipulated.

7. You can move back to the previous screen from any screen by moving the bottom right button.
