Compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have longer wavelength and equal speed longer wavelength and higher speed shorter wavelength and equal speed shorter wavelength and higher speed

C ) shorter wavelength and equal speed

That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.

This can be seen by the reaction given below:

h= Planck's constant

c=speed of the light

 =frquency

=wavelength

So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
