Answer:
The light wave has a longer wavelength and has the greater speed.
Explanation:
light has a far more greater speed than sound. The speed of sound in air is about 343m/s while that of light is around
wavelength (λ) =
since the frequencies of sound and light are same from the question, the wavelength would depend on the magnitude of their velocities. Light with a higher speed would have a longer wavelength.
