"This ray has at least one venomous spine located near the base of the tail behind the dorsal fin; some have up to 3 spines." MarineBio.org
No, rays are not poisonous. However, some ray species have venomous spines that can cause painful stings if they come into contact with a person. It's important to be cautious when handling rays to avoid getting stung.
In the field of physics, that rather depends on the frequency. Optics in the case of light waves; Acoustics in the case of audio (pressure/velocity) waves; radio-physics in the case of radio waves; and Geophysics in the case of seismic waves. I presume you do not inquire after Sting Rays.
Gamma rays have a higher frequency than X-rays.
X-rays have lower energy than gamma rays. Gamma rays are a form of high-energy electromagnetic radiation, while x-rays have lower energy and shorter wavelengths than gamma rays.
Some types of rays include manta rays, stingrays, and electric rays. Manta rays are large, graceful creatures found in the ocean, while stingrays are known for their venomous barbs. Electric rays can produce electric shocks to defend themselves or hunt for prey.
