Question

Find the momentum of a photon with a wavelength of 1.55m (radio wave)

Answer 1

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) =
`6.63*10^(34) J.s`

Formula:

`P = h / \Lambda`

Solving:

`P = h / \Lambda`

`P = (6.63*10^(34))/(1.55)`

`\boxed{\boxed{P \approx 4.27^(34) J.s/m}}\end{array}}\qquad\quad\checkmark`
