Rays are classified as fish.
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
Yeah! They are FISH!
Hard x-rays have a higher or faster frequency than soft x-rays.
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.
Yes
