Q1. Long distance radio broadcasts use short-wave bands because
Answer : Option B
Explaination / Solution:
No Explaination.


Q2. The gases which are transparent to solar radiation but retain long wave heat radiations are called
Answer : Option A
Explaination / Solution:

A greenhouse gas (often abbreviated as GHG) is a gas that both absorbs and emits radiation in the infrared range, commonly called thermal radiation or heat. When present in the atmosphere, these gases trap radiation in the form of heat, causing a warming process called the greenhouse effect. These gases are transparent to solar radiation.
