Microwaves are one part of the electromagnetic spectrum. Name one other part of the electromagnetic spectrum that can be used for cooking food. Identify the part of the electromagnetic spectrum that has a lower frequency than microwaves. Explain why excessive exposure to microwaves can harm human body cells.
Understand the Problem
The question is asking about the electromagnetic spectrum, specifically about microwaves. It requires the user to provide an alternative part of the spectrum used for cooking, identify a part with lower frequency, and explain the effects of excessive microwave exposure on human cells.
Answer
(a) Infrared radiation, (b) Radio waves, (c) Can cause tissue heating and damage.
The final answer is (a) Infrared radiation, (b) Radio waves, (c) Microwaves can cause heating of body tissues, potentially leading to burns and heat-related injuries.
Answer for screen readers
The final answer is (a) Infrared radiation, (b) Radio waves, (c) Microwaves can cause heating of body tissues, potentially leading to burns and heat-related injuries.
More Information
Infrared cooking is often associated with grilling and broiling. Radio waves have a lower frequency than microwaves. Exposure to high microwaves can cause dielectric heating, which is damaging to tissues.
Tips
A common mistake is assuming all electromagnetic radiation is harmful at low levels. Microwaves mainly cause thermal effects.
