Textbook Question
Chapter 30, Problem 4TE
Why is it important that mountain climbers wear sunglass and use sunblock even when the temperature is below freezing?
Expert Solution & Answer
To determine
The importance of wearing sunglass and the use of sunblock at temperature below freezing point.
Answer to Problem 4TE
The mountain climber wears sunglasses and uses sunblock even when the temperature is below freezing because of harmful UV radiation.
Explanation of Solution
Due to the Ultraviolet radiation generated by the sunlight, the mountain climber wears sunglasses and also uses sunblock when the temperature is below the freezing point.
At the higher altitudes, the Ultraviolet radiation intensity increases very fast as compared to the lower altitudes. The high intensity of Ultraviolet radiation rays causes sunburn and damages the eyes. So the sunglass is very important to protect the eyes from the sunlight, which comes directly from the reflection due to ice sheets.
Conclusion:
Therefore, the mountain climber wears sunglasses and uses sunblock even when the temperature is below freezing because of harmful Ultraviolet radiation.
