Correct statements: 1, 4, and 5.
- Everyday items, such as microwaves and cell phones, use the electromagnetic spectrum. — True (they use microwave and radio-frequency parts of the spectrum).
- The Sun emits radiation in the electromagnetic spectrum. — True (the Sun emits across radio to gamma, including visible light).
- The light humans see is a portion. — True (visible light is only a small portion of the full electromagnetic spectrum).
Incorrect statements:
- The electromagnetic spectrum is only used when exploring space. — False (it's used everywhere on Earth in communications, heating, lighting, medical imaging, etc.).
- Only stars emit electromagnetic radiation in the electromagnetic spectrum. — False (many sources emit EM radiation: planets, human bodies, electronic devices, lamps, radioactive sources, and more).
