Correct choices:
- Waves with a higher frequency have a shorter wavelength.
- They all move at the same speed. (in vacuum — the speed of light)
- They can travel through space.
Why: for electromagnetic waves c = f·λ, so increasing frequency reduces wavelength. All EM waves travel at the same speed in vacuum (the speed of light) and therefore can propagate through empty space. The statements about traveling only through matter and higher frequency → longer wavelength are incorrect.
