Question

rank in order from highest frequency to lowest frequency.
column a

1. microwaves
2. radio
3. x - ray

column b
a. highest frequency
b. lowest frequency
c. middle frequency

Explanation:

Step1: Recall electromagnetic spectrum frequency order

In the electromagnetic spectrum, from highest to lowest frequency: Gamma rays > X - rays > Ultraviolet > Visible light > Infrared > Microwaves > Radio waves.

Step2: Match the given waves

X - Ray has a higher frequency than Microwaves, and Radio has the lowest frequency among the three. So X - Ray (highest among the three), Microwaves (middle), Radio (lowest).

Answer:

1. c, 2. b, 3. a
