Which instrument spreads white light into a spectrum so colours can be studied separately?
Q1. Which instrument spreads white light into a spectrum so colours can be studied separately?
Answer: Prism spectroscope
Explanation: A prism spectroscope uses refraction through a glass or crystal prism to disperse white light into its component wavelengths (colours), since shorter-wavelength violet light is refracted more than longer-wavelength red light. A stethoscope detects body sounds, a seismograph measures ground motion, and an anemometer measures wind speed — none of these produce optical spectra.
