The correct answer to this question is B. EMR, and EM radiation is both abbreviations for electromagnetic radiation. This radiation is about waves of the electromagnetic field. The waves occur in space and carry radiant energy.
They were first discovered in the 19th century by William Herschel, who was an astronomer. There are several examples of electromagnetic radiation, including gamma rays and microwaves. As the illustration shows, B represents a shorter wavelength because it has the most frequency compared to the rest. This question is one that a physics student may have to answer on a physics test.
The answer to this question is B. What is electromagnetic energy in the first place? There are some people who may become confused about what this is. This is a type of energy that can describe different forms of energy that is released into space.
There are some items that people use right now that are known to produce this type of energy such as the microwave that a lot of people have at home. Electromagnetic energy is also apparent whenever the Xray is used. There are some old cellular phones that also made use of infrared in order to send data to other phones with infrared also turned on.
