Virtual Booth

The purpose of this project is to test the effectiveness of blue light and green light on whiteboard in order to increase visibility. Firstly, this situation occurred at our college during the evening extra class from 2:30 pm to 4:30 pm. Due to the college building's hillside position, there is insufficient natural light, making it challenging for light to enter the classroom located between the hills. Consequently, students tend to lose focus and easily fall asleep in class. We've learned that green and blue light have shorter wavelengths and higher frequencies, resulting in increased visibility. In physics, longer wavelengths take longer to travel, while shorter wavelengths have better resolution. This is due to the interactions of light with objects, where it can be absorbed, refracted, diffracted, or reflected. In conclusion, our findings indicate that the illumination of green and blue light by our GlowyBoard contributes to enhanced visibility of the writing, reduces eye strain, and mitigates sleepiness.
