Answer? If u can show work if not it’s fine

E = 2.4×10⁻¹⁴J

Frequency =0.36×10²⁰ Hz

Explanation:

Given data:

Wavelength of light = 8.22×10⁻¹² m

Frequency of light = ?

Energy of light = ?

Solution:

peed of light = wavelength× frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s =  8.22×10⁻¹² m  × frequency

Frequency = 3×10⁸ m/s / 8.22×10⁻¹² m  

Frequency =0.36×10²⁰ s⁻¹

s⁻¹ = Hz

Frequency =0.36×10²⁰ Hz

Energy of light:

Formula:

E = hf

h = planks constant = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

E = 6.63×10⁻³⁴ Js × 0.36×10²⁰s⁻¹

E = 2.4×10⁻¹⁴J

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
