The application of optics in real life

Medicine: Utilizing ultraviolet radiation for sterilization, taking X-ray films, and examining patients' injuries.

Agriculture: Photosynthesis of plants, exploring the photosensitive characteristics of various plants to different lights, and studying which type of light is suitable for plant photosynthesis.

JUN matter: Manufacturing laser weapons with extremely strong penetrating ability. Infrared remote sensing technology allows for tracking.

Technology: Ordinary light cannot reach very far. When measuring the distance between celestial bodies, lasers can be used. Lasers can reach the moon.

Life: Manufacturing solar cells, silicon photovoltaic cells, addressing the energy crisis. Producing nanomaterials, and other high-tech materials.

现在到处都是摄像的，马路、小区监控、汽车、智能家居、户外运动等，有前景！
