Answer:
reflection is the act of reflecting or the state of being reflected while echo is

Answer:
Based on the Big Bang Theory, the universe should have radiation of the remnant heat from the initially very hot universe called the Cosmic Microwave Background, CMB, which is presently at a temperature of 2.725° above absolute zero temperature (approximately 3 K)
The blackbody spectrum of colder objects have progressively longer wavelengths. At the temperature of 3 K the microwave radiation is the most intense radiation emitted due to the motion of the elementary particles of an object
Therefore, a 3 k thermal radiation should be microwave
