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:
The wavelength decreases
Explanation:
As you go along the EM spectrum from radio waves to gamma rays, the wavelength decreases as the wave's energy and frequency increase.

Use factor label method in order to determine the amount of atoms, make sure the units cancel.</span>
Answer:
The sun is yellowish in color
Explanation:
The Sun is the closest star to the Earth.
The Sun is more than a couple million miles from other stars.
The Sun is not a white dwarf, but will become one in the future.
The Sun IS a yellowish color so.....
Answer:
-514 kJ/mol
Explanation:
The bond enthalpy which is also known as bond energy can be defined as the amount of energy needed to split one mole of the stated bond. The change in enthalpy of a given reaction can be estimated by subtracting the sum of the bond energies of the reactants from the sum of the bond energies of the products.
For the given chemical reaction, the change in enthalpy of the reaction is:
Δ [2(409) + 4(388) + 3(496) - 4(630) - 4(463)] kJ/mol = 818 + 1552 + 1488 - 2520 - 1852 = -514 kJ/mol
