High energy waves have a. a short wavelength b.a long wavelength c.neither a short nor a long wavelength d. no waves

Respuesta :

High energy means short wavelength Low energy means long wavelength 
Well.. D is automatically out because they wouldn't call it a high energy wave if there weren't any waves! The more amount of energy there is, the higher the frequency. 

And well, the higher the frequency - the shorter the wave! =)
