Respuesta :
The red light appears first in the visible light spectrum as it exhibits the longest wavelength, and is refracted the least.
The relation between wavelength and refraction of light:
The phenomenon of bending of light as it moves from one medium to another is termed refraction. The intensity of refraction enhances with the decrease in the wavelength of light. The shorter wavelengths of light, that is, blue and violet are slowed more and at the same time experience more bending in comparison to the lights of longer wavelengths, that is, red.
The red color exhibits the longest wavelength and the slowest vibration, on the other hand, violet color exhibits the shortest wavelength and the fastest vibration of energy. The longer the wavelength, the less it is refracted and vice versa, This is the reason that red light appears first in the visible light spectrum.
Thus, the correct answer is option D.
