There the protons and the nuetrons
Explanation:
It is known that relation between wavelength and frequency is as follows.

where,
= wavelength
c = speed of light = 
[/tex]\nu[/tex] = frequency
It is given that frequency is
. Hence, putting this value into the above formula and calculate the wavelength as follows.


= 
or, = 
Thus, we can conclude that wavelength of given radiation is
.
Answer is: polystyrene.
Expanded polystyrene is used to manufacture foam cups.
Polystyrene production is several million tonnes per year.
Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.
Styrene (ethenylbenzene) is an organic compound with the chemical formula C₆H₅CH=CH₂. It is a colorless oily liquid.
So the first one is yellow and the other one is white
A scientist would most likely need to update her model when it no longer supports the latest results.
