What can the longest wavelength be the size of?

Radio: Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can range from less than one centimeter to greater than 100 meters (this is bigger than the size of a football field).

How to find the longest wavelength of electromagnetic radiation?

Lower frequencies have longer wavelengths and higher frequencies have shorter wavelengths. Within the visible light spectrum, red has the lowest frequency and therefore the longest wavelength. Frequencies going lower enter the non-visible infrared range.

Which string has the longest wavelength?

Radio waves have the longest wavelength of all electromagnetic waves.

How do varying frequencies affect the wavelength of a wave?

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
