Properties of EM Waves: Practice Problem & Solution

What is the cause of "Green house effect": (2002)
Infra-red rays
Ultra violet rays
X-rays
Radio waves

Solution Explained:

To solve this problem, we apply the core principles of Properties of EM Waves. Understanding the underlying formula is key to arriving at the correct answer below:

The greenhouse effect is primarily caused by greenhouse gases in the atmosphere absorbing and re-radiating infra-red rays (heat) back towards the Earth's surface, trapping the heat.
