Light spectrum triangular prism kit for teaching optics. The set includes glass triangular prisms designed for light refraction and spectrum demonstrations. Lightweight and portable for easy transport and storage, and it includes a triangular prism with holder for safe, stable demonstrations. Key benefits Easy to operate and simple to use, supporting handson physical experiment learning. Glass prisms deliver clear dispersion for accurate observation of the light spectrum. Lightweight and portable, convenient to carry between classroom, lab, or tutoring sessions, with easy storage when not in use. Safe and practical for physics teaching, with a stand to support stable demonstrations. Attributes and usage Function: light spectrum demonstration, refraction experiments, and optical teaching exercises. Material: glass triangular prisms for reliable optical performance. Set composition: triple or multiple triangular prisms with holder/stand for secure display. Performance: designed for practical, easytouse light refraction and spectrum experiments in educational settings. Practical use scenarios Classroom demonstrations to show how white light splits into spectrum through a prism. Student lab work or tutoring sessions to explore refraction angles and dispersion in a handson setting. Science fair projects requiring a stable prism setup to illustrate light dispersion and spectrum concepts.
