Question

which of the following types of light has the shortest wavelength?
radio
infrared (ir)
ultraviolet (uv)
x - ray

Explanation:

Step1: Recall the electromagnetic spectrum

The electromagnetic spectrum from longest to shortest wavelength is: Radio waves > Infrared > Ultraviolet > X - rays.

Step2: Compare the given options

Among Radio (a), Infrared (IR - b), Ultraviolet (UV - c), and X - ray (d), X - ray has the shortest wavelength.

Answer:

d. X - ray
