Which of the following parts of the electromagnetic spectrum have longerwavelengths than those witnessed in the visible spectrum? 

       A. Gamma rays   B. Infrared   C. Cosmic waves   D. X-rays

Respuesta :

Infrared radiation is the only one with wavelengths longer than the wavelengths of visible light. X-rays and gamma rays are known to be shorter than visible wavelengths, and cosmic waves are only high energy particles. I hope this helped. And sorry about the late answer...
