Which of the following are not electromagnetic waves?
[AIEEE 2002]
(a) Cosmic Rays (b) Gamma Rays
(c) Beta Rays (d) Gamma Rays
Explain also.
beta rays is the answer..they are just fast moving electrons, and are not electromagnetic....
cosmic rays were thought to be electromagnetic, but actually they are not in electromagnetic spectrum.. (i am unable to explain that )
so someone please explain that part..are cosmic rays electromagnetic??
THE FOUTH OPTION IS "X-RAYS".
SOLUTION
The correct answer is beta rays.
Cosmic rays even they dont lie in an electromagnetic spectrum are electronegative. They have high-energy charged particles that travels through space at nearly speed of light. Their extremely high energies are compared to those of gama rays at the upper end of electromagnetic spectrum.
While beta rays are not electromagnetic. They are just fast moving electrons rather.
