Physics MCQ on Radio Wave Propagation for NEET, JEE, Medical and Engineering Exam 2021

MCQ on Radio Wave Propagation: Previous trends reveal that NEET/JEE aspirants find Physics as the most challenging section amongst the other sections. But most of them fail to decipher the reason behind this. This particularly can be as the candidates taking up this examination are predominantly medical aspirants with their subject of interest being Biology. Also, sections like Physics are more on theories, laws, numerical as opposed to Biology which is more of fact-based, life sciences and comprising of substantial explanations.
