Question

2 which description applies to light? choose four. behaves like a wave behaves like a particle travels faster than anything in the universe needs to travel through matter cannot travel through matter is a form of energy

Explanation:

1. Light exhibits wave - particle duality, so it behaves like a wave (supports phenomena like interference, diffraction) and behaves like a particle (photons, supports phenomena like photoelectric effect).
2. The speed of light in a vacuum is the fastest speed in the universe, so it travels faster than anything in the universe.
3. Light is a form of electromagnetic radiation, which is a form of energy.
4. Light does not need to travel through matter (it can travel through a vacuum), and it can travel through some matter (like air, glass to some extent), so "needs to travel through matter" and "cannot travel through matter" are incorrect.

Answer:

• Behaves like a wave
• Behaves like a particle
• Travels faster than anything in the universe
• Is a form of energy
