No, the frequency and wavelength of light do not change as it moves through space at high speeds. According to the theory of special relativity, the speed of light in a vacuum is constant and independent of the motion of the source or the observer. This principle is known as the constancy of the speed of light.
Due to this constancy, the frequency and wavelength of light remain the same regardless of the relative motion between the source of light and the observer. This phenomenon is known as the Doppler effect, which is commonly observed in the context of sound waves. However, unlike sound waves, the Doppler effect does not affect the frequency or wavelength of light as it moves through space.
In other words, if an observer is moving towards or away from a light source, the observer will measure the same frequency and wavelength of light as an observer who is stationary relative to the source. This principle has been extensively verified by experiments and is a fundamental aspect of our understanding of light and its behavior.
