Base your answers to questions 6 through 8 on the diagrams below and on your knowledge of Earth science. The diagrams represent electromagnetic waves being transmitted (T) by a Doppler radar weather instrument and waves being reflected (R) by rain showers. This instrument produces computer images that show the movement of rainstorms.
The computer image below shows a rainstorm over Texas. Letters A and B represent locations on Earth’s surface.
If Doppler radar is used at locations A and B, as this rainstorm moves eastward, reflected wavelengths from this storm will be

• shorter at both locations A and B
• longer at both locations A and B
• shorter at location A and longer at location B
• longer at location A and shorter at location B
