How does the wavelength of light determine its perceived color?
Answer
Color is determined by the frequency and spacing of light wave crests
Light behaves as a wave, similar to ripples in a pond. The color of light is defined by the distance between its wave crests, known as the wavelength. Violet light has short, tight waves with high frequency, while red light has longer, stretched-out waves with lower frequency. When astronomers observe light, they analyze these specific wavelengths to determine the object's properties, as every color corresponds to a precise measurement.
