Explanation: Solar radiation that has not been absorbed or scattered and reaches the ground from the sun is called direct radiation or beam radiation.

What is renewable energy physics?

Renewable energy is defined as energy that is collected from resources that will never run out or which are replaced by nature in less than a human lifetime. Non-renewable energy is defined as energy collected from resources that cannot be replaced when they are used up, such as oil, natural gas or coal.
