Question
Why does light travel faster in air than in water?
1 pts
• Air is a lower-density medium than water
• Water reflects more light than air
• Light is absorbed by water, slowing it down
• Water causes light to change direction, making it travel slower
Question 2
What is the electromagnetic (EM) spectrum?
1 pts
• A range of waves with varying frequencies and wavelengths, including visible light, radio waves, and x-
rays
• A type of mechanical wave that only travels through air
• A type of sound wave
• A range of visible light waves

### Question 1
Why does light travel faster in air than in water?
- **Correct Answer**: **Air is a lower-density medium than water**
Light travels faster in media with lower optical density. Since air has a lower density than water, light travels faster in air.

### Question 2
What is the electromagnetic (EM) spectrum?
- **Correct Answer**: **A range of waves with varying frequencies and wavelengths, including visible light, radio waves, and x-rays**
The electromagnetic spectrum encompasses all types of electromagnetic radiation, which includes not just visible light but also radio waves, ultraviolet light, x-rays, and more, organized by frequency and wavelength.
