Explain the types of sound waves based on its frequency, Give an example for each. (a) What is the maximum electric field strength in an electromagnetic wave that has maximum magnetic field strength of about 10 times of Earth’s magnetic field? Given earth’s magnetic field = 5.00×10−5T (b) Write any two properties of electromagnetic wave.
