The frequency of a wave is inversely proportional to its wavelength. This means that as the frequency increases, the wavelength decreases, and vice versa.
Information/energy can travel through different mediums at different frequencies. In general, higher frequencies tend to travel faster and with less interference, while lower frequencies may experience more obstacles and interference.
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Different frequencies are used for different types of communication and technologies. For example, radio waves are used for radio and television broadcasting, while microwaves are used for cell phone and satellite communication. Higher frequencies also have the potential to carry more data, which is important for technologies like wireless internet and streaming services.
Some frequencies, such as ultraviolet and X-rays, can be harmful to our health if we are exposed to them in large doses. However, most frequencies that we encounter in our daily lives, such as visible light and radio waves, are not harmful to us. The impact of different frequencies on our health is still an area of ongoing research.
