Question:

Rank these electromagnetic waves on the basis of their speed (in a vacuum). Rank from fastest to slowest. AM radio wave green light X-ray Yellow light infrared light FM radio wave

Answer:

all the light waves have the same speed, c; The speed of light in a vacuum
vAM radio = vFM radio = vinfrared = vyellow = vgreen = vX-ray
