The energy and momentum of a photon can be calculated using the equations:
E=hc/(λ)
Energy(λ) of a photon (E) = Planck's constant (h) × Speed of light (c) / Wavelength (λ)
And
P=h/(λ)
Momentum of a photon (p) = Planck's constant (h) / Wavelength (λ)
Given that the wavelength of the photon is 700 nm (nanometers), we can substitute this value into the equations.
First, let's calculate the energy:
E = (6.626 × 10^-34 J·s) × (3.0 × 10^8 m/s) / (700 × 10^-9 m)
E ≈ 2.84 × 10^-19 Joules
The energy of the photon is approximately 2.84 × 10^-19 Joules.
Next, let's calculate the momentum:
p = (6.626 × 10^-34 J·s) / (700 × 10^-9 m)
p ≈ 9.46 × 10^-28 kg·m/s
The momentum of the photon is approximately 9.46 × 10^-28 kg·m/s.
