Question

What is the wavelength of a photon with a momentum of 5.00 × 10⁻29 kg⋅m/s?

a) 4.00 × 10⁴ nm
b) 8.01 × 10⁻38 nm
c) 1.24 × 10⁻11 eV
d) 2.48 × 10⁻29 eV

Answer 1

The wavelength of the photon is approximately 1.33 × 10⁶ meters.

Step-by-step explanation:

To find the wavelength of a photon with a momentum of 5.00 × 10⁻²⁹ kg⋅m/s, we can use the equation:

wavelength = Planck's constant / momentum

Plugging in the values, we have:

wavelength = (6.63 × 10⁻³⁴ m² kg/s) / (5.00 × 10⁻²⁹ kg⋅m/s)

wavelength ≈ 1.33 × 10⁶ meters

Therefore, the wavelength of the photon is approximately 1.33 × 10⁶ meters.
