Question

which types of electromagnetic waves have frequencies that are higher than those of ultraviolet light but lower than those of gamma rays?
○ microwaves
○ x - rays
○ infrared light
○ radio waves

Explanation:

To solve this, we recall the electromagnetic spectrum order by frequency (increasing order): radio waves, microwaves, infrared, visible light, ultraviolet, X - rays, gamma rays. We need waves with frequency higher than ultraviolet (UV) and lower than gamma rays.

• Microwaves: Frequency lower than UV. Eliminate.
• X - rays: Frequency is between UV and gamma rays.
• Infrared light: Frequency lower than UV. Eliminate.
• Radio waves: Frequency lower than UV. Eliminate.

Answer:

B. X - rays
