How are herschel and ritter experiments similar?

Herschel and Ritter's experiments both investigated the nature of light and its interaction with materials, contributing to the understanding of the electromagnetic spectrum. Herschel discovered infrared radiation by using a prism to analyze sunlight, while Ritter explored ultraviolet light by examining the effects of sunlight on silver chloride. Both experiments emphasized the invisible aspects of the light spectrum beyond the visible range, showcasing the broader implications of light beyond human perception. Their work laid foundational principles for the study of spectroscopy and photochemistry.
