1 percent of the solar radiation
λ = h/p = h/mv; where λ represents the wavelength in meters, h denotes Planck's constant = 6.6261 × 10^-31 J/s, m symbolizes the mass (in kg), and v indicates the velocity in m/s.
The velocity is: 2.0 × 10^5 m/s
1 amu equals 1.66 × 10^-24 g
So, 19.992 amu translates to = 1.66 × 19.992 × 10^-24 g
= 3.319 × 10^-23 g
Consequently; λ= (6.6261 × 10^-31)/(3.319×10^-23)×2×10^5)
= 1.0 × 10^-13 m
