Nastasia [14]2 years ago
7 0

Answer:

9.00  

Explanation:

Data:

[H⁺] = 1.0 × 10⁻⁹ mol·L⁻¹

Calculation:

pH = -log[H⁺] = -log(1.0 × 10⁻⁹) = -log(1.0) - log(10⁻⁹) = -0.00 - (-9) = -0.00 + 9 = 9.00

What happens to the number of waves when you decrease the wavelength?
Keith_Richards [23]

C

Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.

Explanation:

The energy of a wave is given by the formula;

E= hf

Whereby;

E = energy

h = Plank’s constant

f = frequency

Remember that f can be also represented as;

¹/ λ

Whereby;

λ = wavelength

Wavelength and frequency are therefore inversely proportional.

Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.
