  1. Question 1

    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?

    • A) A periscope changes viewing angle with mirrors
    • B) A spectroscope or prism setup spreads light into its colours
    • C) A laser pointer emits nearly one wavelength only
    • D) A fibre optic cable guides light by total internal reflection

    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).
