Question

which forms of electromagnetic radiation are arranged in order of increasing energy? (1 point) microwaves, infrared, ultraviolet, gamma rays gamma rays, ultraviolet, microwaves, infrared microwaves, ultraviolet, infrared, gamma rays infrared, gamma rays, microwaves, ultraviolet

Explanation:

To determine the order of electromagnetic radiation by increasing energy, we use the relationship \( E = h
u \) (energy is proportional to frequency) and the electromagnetic spectrum order (from lowest to highest energy: radio, microwaves, infrared, visible, ultraviolet, X - rays, gamma rays).

• Option 1: microwaves (low energy), infrared (next), ultraviolet (higher), gamma rays (highest) – follows the increasing energy order.
• Option 2: Starts with gamma rays (highest energy), which is incorrect for increasing order.
• Option 3: Infrared should come before ultraviolet in the low - to - high energy sequence, so this is wrong.
• Option 4: The order is jumbled (gamma rays are highest, but placed second; microwaves are low but placed third), so it's incorrect.

Answer:

A. microwaves, infrared, ultraviolet, gamma rays
