Calculate the frequency of a wave with a wavelength of 5.62 x 1010 m. (first convert m to nm)

Readme [11.4K]

Answer:

f = 0.534×10⁻² Hz

Explanation:

Given data:

Frequency of wave= ?

Wavelength of wave = 5.62×10¹⁰ m

Solution:

Formula:

Speed of wave = wavelength × frequency

Speed of wave = 3×10¹⁷ nm/s

λ = 5.62×10¹⁰m×10⁹ nm/1 m = 5.62×10¹⁹ nm

Now we will put the values in formula.

3×10¹⁷ nm/s = 5.62×10¹⁹ nm × f

f = 3×10¹⁷ nm/s / 5.62×10¹⁹ nm

f = 0.534×10⁻² s⁻¹ or

f = 0.534×10⁻² Hz

Lemon juice has a pH of about 2.0, compared with a pH of about 1.0 for stomach acid. Therefore, the concentration of H+ in stoma

LuckyWell [14K]

Answer:

The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.

Explanation:

The H⁺ concentration of a solution is exponentially related to its pH value:

$\rm [H^{+}] = 10^{-pH}$ .

For lemon juice:

$\rm [H^{+}] = 10^{-2.0} = 0.01\; M$ .

For stomach acid:

$\rm [H^{+}] = 10^{-1.0} = 0.1\; M$ .

Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
