<h2>
Answer: 1.22 × 10⁻¹ m</h2>
<h3>Explanation:</h3>
Wavelength = Speed of Light ÷ Frequency
= (2.99 × 10⁸ m/s) ÷ ( 2.45 × 10⁹ /s)
= 1.22 × 10⁻¹ m
The wavelength of a light of frequency 2.45 × 10⁹ /s is 1.22 × 10⁻¹ m.
<u>Notes:</u>
Hz ≡ /s
The correct answer is Charle's law. This law law states that the pressure and absolute temperature of a fixed quantity of gas ate directly proportional under constant volume conditions. It is expressed as V/T = C where is some constant that is constant for all conditions given that pressure is constant.

Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.
One example of a molecule is (chlorine).
Examples of a compound is NaCl (sodium chloride) or (water)
Answer:
Troposphere
Explanation:
The troposphere is the lowest layer of Earth's atmosphere that extends from under the stratosphere down to the surface of the earth. Nearly all weather condition takes place in the troposphere. The troposphere contains about 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols in the atmosphere.
