2. In a transverse wave, how do the vibrations relate to the direction of energy transfer?
- A. Parallel to it
- B. Perpendicular to it
- C. At 45° to it

- D. Gamma rays
5. A star is moving away from Earth. How does this affect the light detected from it, and why?
- A. The observed wavelength decreases (blue-shifts) due to the Doppler effect
- B. The observed wavelength increases (red-shifts) due to the Doppler effect
- C. There is no change, as light speed is constant for all observers
- D. The observed frequency increases while wavelength stays the same
