Rays are classified as fish.
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
Hard x-rays have a higher or faster frequency than soft x-rays.
Yeah! They are FISH!
no. cartilaginous fishes are sharks and rays.
The 'soft' and 'hard' refer to the energy of the x-rays used to perform the spectroscopy. Hard x-rays are higher energy x-rays than soft x-rays. Where to draw the line for when an x-ray stops being 'hard' and becomes 'soft' is rather arbitrary but most people would agree I think that x-rays of energy ~ 1500 eV and less are 'soft' x-rays and above ~ 2500 eV are 'hard' x-rays.
Hard x-rays have wavelengths below 0.2nm-0.1nm .Soft X rays have wavelengths above.
Angelfish which haa a diet of algae, worms, shellfish, shrimp, and sponges. the other is Butterflyfish which feeds on soft coral,plankton, and small crustaceans.
Yes. Grenz rays are 'soft' i.e. low-energy X-rays.
They are Saltwater fish.
Yes. Manta rays are fish belonging to the class Chondrichthyes, which also includes sharks.
Ceratotrichia are the fine, flexible rays found in the fins of a perch and other bony fish. Their primary function is to provide structural support and stability to the fins, allowing for effective movement and maneuverability in the water. These rays help to maintain the fin's shape during swimming, facilitating propulsion and aiding in the fish's ability to change direction quickly. Additionally, ceratotrichia play a role in the overall hydrodynamics of the fish, enhancing its swimming efficiency.
