Answer :
Locating stars hidden by nebulae that would typically obscure other stars.
- Unlike other waves in the electromagnetic spectrum, radio waves have huge frequencies. Since they are significantly larger than an atom and have a large wavelength, atomic nuclei cannot obstruct or deflect them. In contrast, gamma rays and other short-wavelength electromagnetic radiation can easily be blocked and deflected by atomic nuclei since they are smaller than atoms. When such radiation passes through a nebula cloud, it is greatly attenuated. Thus, this obstacle is circumvented by radio waves.
- Radio waves are an electromagnetic radiation type that are most commonly used in communication devices like radios, mobile phones, and televisions. These gadgets take in radio waves and transform them into sound waves by causing mechanical movements in the speaker.
