How does the wavelength of violet light compare to that of red light?

It is the same
It is longer
It is shorter
It is brighter

The correct answer is: It is shorter

The wavelength of violet light is shorter compared to that of red light. In the visible light spectrum, light is grouped according to its wavelength, with violet having the shortest wavelength, typically ranging from about 380 to 450 nanometers, while red light has a longer wavelength, approximately between 620 to 750 nanometers. This relationship between color and wavelength is a fundamental concept in the study of light and optics, reinforcing the idea that as you move from violet to red in the spectrum, the wavelength increases. Recognizing this difference is crucial for various applications, including understanding light behavior in different mediums and designing optical devices.
