A chemistry teacher shows students that white light splits into a spectrum through a glass prism. Which simple optical tool separates wavelengths without a diffraction grating machine?
Q1. A chemistry teacher shows students that white light splits into a spectrum through a glass prism. Which simple optical tool separates wavelengths without a diffraction grating machine?
Answer: A spectroscope or prism setup spreads light into its colours
Explanation: A glass prism refracts white light by different amounts for each wavelength (dispersion), separating it into the visible spectrum from red (least refracted) to violet (most refracted).
