Answer :

Their wavelength (b) Speed is 340 m/s. Speed/frequency = 340/300 = 1.13 m, where wavelength is equal to these two quantities. The separation between two successive wave crests or troughs is known as a wavelength.

At 300 GHz 3 Hz, what EM wave is it?

The electromagnetic spectrum's longest-wavelength waves are radio waves. These electromagnetic waves range in frequency from 300 GHz to 3 kHz, yet they are sometimes referred to as microwaves when their frequency is greater than 3 GHz.

What exactly are wavelengths and frequencies?

The wavelength is the separation between two wave crests; it also applies to wave troughs. The frequency is expressed in cycles per second and represents the number of vibrations that cross a specific area in a second (Hertz).
