Question

5 multiple choice 5 points which of the following electromagnetic radiations has the shortest wavelength? ultraviolet visible infrared radio 6 multiple choice 5 points which type of wave requires a material medium through which to travel? electromagnetic infrared sound radio

Explanation:

• Question 5: In the electromagnetic spectrum, the order of increasing wavelength is: gamma rays < X - rays < ultraviolet < visible < infrared < microwaves < radio waves. So, ultraviolet has a shorter wavelength than visible, infrared, and radio.
• Question 6: Electromagnetic waves (including infrared and radio waves) can travel through a vacuum. Sound waves are mechanical waves and require a material medium (solid, liquid, or gas) to travel.

Answer:

1. ultraviolet
2. sound
