Where "λ" (lambda) is the wavelength, "h" is the Planck constant, and "p" is the momentum. Then we have to
P = h / λ
Data:
P (momentum) = ?
λ (wavelenght) = 1.55 m
h (Planck constant) = [tex]6.63*10^{34} J.s[/tex]
Formula:
[tex]P = h / \Lambda[/tex]
Solving:
[tex]P = h / \Lambda[/tex]
[tex]P = \frac{6.63*10^{34}}{1.55} [/tex]
[tex]\boxed{\boxed{P \approx 4.27^{34} J.s/m}}\end{array}}\qquad\quad\checkmark[/tex]
