What frequencies do short and long wavelengths have

Dear Student,

Please find below the solution to the asked query:

Short wavelength is the wavelength shorter than some predefined wavelength for a particular type of wave. For example in electromagnetic wave ultraviolet, x-ray have shorter wavelength than visible light. 
They have high frequencies. 

Long wavelength is the wave having wavelength longer than predefined limit. Like infrared, or radio wave have longer wavelength than visible light. They have low frequencies.
