It seems like you want to calculate the wavelength (λ) using the energy threshold and the Planck-Einstein relation. The formula for this is:

λ = h*c / E

where:
- h is Planck's constant (6.62607015×10^-34 m^2 kg/s)
- c is the speed of light (3×10^8 m/s)
- E is the energy threshold (8.01×10^-19 J)

Substituting the values into the formula, we get:

λ = (6.62607015×10^-34 m^2 kg/s * 3×10^8 m/s) / 8.01×10^-19 J

Now, you just need to perform the calculation to find the wavelength.
