yes
They are both electromagnetic energy, so it that light (he, he) they are the same. But the gamma rays are of much higher frequency, and that means shorter wavelength and higher energy. As we move up...
I don't think so..... But there is an artist called Billy Ray Cyrus.
Yes, provided it is the ray. If AB is a vector then the answer is no.
Yes. They are both high up in the electromagnetic spectrum, with short wavelengths and high frequency.
