Final answer:
The statement is true; waves that are "blue shifted" have shorter wavelengths compared to "red shifted" waves, a concept related to the Doppler effect in the context of electromagnetic radiation.
Step-by-step explanation:
The statement is true. Waves that are "blue shifted" do indeed have shorter wavelengths than those that are "red shifted". This phenomenon is directly related to the Doppler effect, where the observed wavelength of waves, such as electromagnetic radiation, from a source moving towards an observer is shorter, resulting in a blueshift. Conversely, if the source moves away from the observer, the observed wavelength is longer, leading to a redshift. This applies not only to visible light but to other types of waves as well, including radio waves and X-rays.
