The correct response is: the frequency of blue light is greater than that of yellow light, while the speeds of both colors of light are the same.
In more detail, light of different colors (different wavelengths) travels at the same speed in a vacuum, which is the speed of light (approximately \(3.00 \times 10^8\) m/s). However, blue light has a shorter wavelength than yellow light, which means that blue light has a higher frequency compared to yellow light, as frequency and wavelength are inversely related (given by the equation \(c = \lambda \nu\), where \(c\) is the speed of light, \(\lambda\) is the wavelength, and \(\nu\) is the frequency).
