I’ve googled the question but I can’t understand any of it.

When I google it I only find brand names and the like. I’ve never heard of an actual “K-ray”.
Can you point to a Google search result?
K-band is a section of the electromagnetic (EM) spectrum within the microwave region with frequencies between about 18-27 GHz ( analogous to how the FM band is a section of the EM within the radio region with frequencies from about 88MHz to 104MHz as seen on your car radio dial.) Waves of these frequencies tend to be used in radars and satellite communications, and I’ve never seen them referred to as a ‘ray’, although they can be formed into a beam.
I think its more likely to be shorthand for an particular type of medical X-Ray. Doctors generate X-Rays by shooting electrons at a metal target. Electrons in the beam and in the target affect one another. Electrons in the target can be imagined as living in increasingly higher energy levels around each target nucleus. One possible X-Ray is formed by an electron dropping from the L energy level in the target metal atoms to the K level. A K-ray would be an example of one of the 2 types of radiation produced in a doctor’s X-ray machine. This one has a lot of a specific frequency of X-ray, while the other type spreads energy through a lot of different frequencies. Both types are important for a range of diagnostic and treatment purposes. The second type is adjustable by the operator. The first type – such as a K Ray – is set by the materials in the target.
