red shifted
True
The wavelengths of visible light are longer than ultraviolet wavelengths.
Violet light has longer wavelengths.
Light energy with wavelengths longer than visible red is infrared light.
have wavelengths that are longer than normal:)
Your question is incomplete -- what does "which" refer to?
electromagnetic waves with a longer wavelength has
Adjust the wavelenght! The higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Basically, the longer the wavelength, the lower the pitch.
It's red.
Yes, it is.
All wavelengths used for communication are longer than all infrared, visible, ultraviolet, and X-ray wavelengths.
No, it does not.
