True. As white light enters a prism, it undergoes dispersion due to varying speeds of different wavelengths. The longer red wavelengths experience less bending than the shorter blue ones, resulting in the separation of colors and the formation of a rainbow spectrum.
Explanation:
Indeed, it is true. When white light enters a prism, its constituent colors undergo dispersion. This phenomenon occurs because different colors of light travel at different speeds in the prism, causing the light to refract at varying angles. Longer wavelengths, such as red, bend less than shorter wavelengths, like blue. Consequently, the light spectrum fans out, creating a vivid display of colors known as a rainbow. This fundamental principle of optics, first elucidated by Sir Isaac Newton, remains a captivating illustration of the inherent properties of light and the intriguing interplay between wavelength and refraction.
