<h2>Answer:    8.69 × 10⁻¹ Hz </h2>

<h3>Explanation: </h3>

Frequency = Speed of Light ÷ Wavelength

                    = (2.99 × 10⁸ m/s) ÷ (3.44 × 10⁻⁸ m)  

                    = 8.69 × 10⁻¹ Hz

The frequency of a light of wavelength 34.4 nm is 8.69 × 10⁻¹ Hz.

<u>Notes:</u>

Hz ≡ /s

1 m = 10⁹ nm

Water is composed of the same elements as hydrogen peroxide why do these substances have different properties
Dmitrij [34]
They have different ratios of elements. Water is H20 and Hydrogen Peroxide is H202. The extra oxygen atom in hydrogen peroxide causes it to be structured and react differently.
