Question

The Earth's atmosphere is transparent to most of the electromagnetic spectrum EXCEPT for a significant portion of which type of radiation, primarily absorbed by the ozone layer?

SUBHANI · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Atmospheric Absorption of Electromagnetic Radiation
 **Related Topics**: Ozone layer, Electromagnetic spectrum, UV radiation
 **Prerequisites**: Basic understanding of the electromagnetic spectrum and the properties of the Earth's atmosphere.
## SOLUTION PATHWAY
**Given Information**:
  The Earth's atmosphere is transparent to most of the electromagnetic spectrum.
  A significant portion of one type of radiation is absorbed by the ozone layer.
**Method & Steps**:
 1. Identify the type of radiation absorbed by the ozone layer.
  Reasoning: The ozone layer is known for its absorption of a specific type of electromagnetic radiation that is harmful to life on Earth.
  Formula/Rule:  No specific formula is needed for this question; it relies on factual knowledge.
 2. Consider the options provided.
  Working:  Visible light passes through the atmosphere relatively unobstructed. Infrared radiation is partially absorbed, but not primarily by the ozone layer. Radio waves are largely unaffected by the atmosphere. Ultraviolet radiation is strongly absorbed by the ozone layer.
  Key Point: The ozone layer's primary function is to protect life from harmful UV radiation.
 3. Select the correct option.
  Result: Ultraviolet (UV) radiation
  Verification: The ozone layer's absorption of UV radiation is a well-established scientific fact.
 ## OPTION ANALYSIS
A :x: Visible Light: The atmosphere is largely transparent to visible light.
B :x: Infrared: While some infrared radiation is absorbed, it is not primarily absorbed by the ozone layer.
C ✓: Ultraviolet: The ozone layer effectively absorbs a significant portion of ultraviolet radiation.
D :x: Radio Waves: The atmosphere is largely transparent to radio waves.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the absorption properties of different atmospheric layers:  Remember the ozone layer's primary role in UV absorption.
  2.Failing to recall the harmful effects of UV radiation: This knowledge helps to connect the ozone layer's function to its absorption of UV radiation.
 **Quick Tips**:
  1.Memorize the basic regions of the electromagnetic spectrum and their interactions with the atmosphere.
  2.Associate the ozone layer with protection from harmful solar radiation.
