Are rays classified as fish?
Rays are classified as fish.
What is the difference between soft x-rays and hard x-rays?
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
Which have more frequency hard X ray or soft x rays?
Hard x-rays have a higher or faster frequency than soft x-rays.
Are rays fish?
Yeah! They are FISH!
Is a tuna fish cartilaginous fish?
no. cartilaginous fishes are sharks and rays.
What is the difference between Soft X-ray Absorption Spectroscopy and Hard X-ray Absorption Spectroscopy?
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.
What is the wave length os soft x-ray and hard x-rays?
Hard x-rays have wavelengths below 0.2nm-0.1nm .Soft X rays have wavelengths above.
Are manta rays herbivores?
No, manta rays are not herbivores. They are filter feeders, using their gill rakers to filter plankton and small fish from the water.
Are grenz rays an example of electromagnetic radiation?
Yes. Grenz rays are 'soft' i.e. low-energy X-rays.
Are spotted eagle rays freshwater fish or saltwater fish?
They are Saltwater fish.
Are manta rays really fish?
Yes. Manta rays are fish belonging to the class Chondrichthyes, which also includes sharks.
What sorts of things are difficult to image with x rays?
Soft tissue such as muscle, fat and internal organs is hard to image using X-rays. This is because X-rays penetrate soft tissue relatively easily.
