Explanation:
The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m
We need to find which wave have a higher frequency.
The relation between frequency and wavelength is given by :
Let f₁ and f₂ be the frequency of wave 1 and wave 2.
And
Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.
Y2O3 is the molecular formula. Yttrium (III) oxide is also called yttria. It is a white substance and is air-stable. The usual application for this compound is a starting material for inorganic compounds and in material science. IT is insoluble in water and has a high melting point.
Answer:
The correct answer is: d-orbital
Explanation:
The transition metals are the chemical elements that belong to the B-group of the periodic table, from group 1B to 8B. The B-group is located between the groups IIA and IIIA in the periodic table.
The general electronic configuration of the chemical elements belonging to this group is (n-1) d¹⁻¹⁰ ns⁰⁻², because of the <u>partially filled d-subshell</u> in the ground state or excited state. <u>Therefore, the transition metals are refereed as the </u><u>d-block elements</u><u>.</u>
Answer: 5 days
Explanation:
1,000,000/2 = 500,000 *do this because of the 2 numbers every second
500,000/60= 8,333.33 *do this to get minutes
8,333.33/60= 138.88 *do this to get hours
138.88/24= 5.7866 *do this to get days
5 days 7 hours 8 minutes 6 seconds
