Final answer:
Infrared radiation has a higher frequency than radio waves but lower than visible light, X-rays, and gamma rays. The correct answer to the student's question is radio waves.
Step-by-step explanation:
Infrared radiation has a lower frequency than visible light but has a higher frequency than radio waves. Electromagnetic radiation includes various types of waves, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, each with distinct frequencies and wavelengths. When comparing infrared radiation to the options provided, it is clear that:
- Visible light has a higher frequency than infrared radiation.
- Radio waves have a lower frequency than infrared radiation.
- Gamma rays have a higher frequency than infrared radiation.
- X-rays also have a higher frequency than infrared radiation.
Therefore, the correct answer to the question is that infrared radiation has a higher frequency than radio waves (B).
