a student created a chart that shows information about the electromagnetic spectrum. electromagnetic radiation practical application gamma used for cooking foods infrared used in night vision goggles radio used for communication by spacecraft ultraviolet used to sterilize medical equipment the student made a mistake on the diagram. which mistake did the student make? a. gamma waves are used in medicine to shrink problem cells, not for cooking foods. b. infrared radiation is used to create energy in nuclear reactors, not in night vision goggles. c. radio waves are used by food companies to sterilize produce, not for communication by spacecraft. d. ultraviolet light is used to communicate information through space, not to sterilize medical equipment.
Answer
# Answer:
A. Gamma waves are used in medicine to shrink problem cells, not for cooking foods.
# Explanation:
## Step1: Recall gamma - wave uses
Gamma waves are high - energy electromagnetic radiation. They are used in cancer treatment (radiation therapy) to target and shrink cancer cells, not for cooking foods.
## Step2: Check infrared - wave use
Infrared radiation is indeed used in night - vision goggles as it can detect heat signatures, not in nuclear reactors for energy creation.
## Step3: Check radio - wave use
Radio waves are used for communication by spacecraft as they can travel long distances through space, not for sterilizing produce by food companies.
## Step4: Check ultraviolet - wave use
Ultraviolet light is used to sterilize medical equipment as it can kill bacteria and other microorganisms, not for space communication. So the mistake is in the use of gamma waves as stated in option A.
