Answer:
Explanation:
The energy of the photon must be equal to 0.1 eV, so let's convert this value into Joules first:
The energy of the photon is related to its frequency by
where h is the Planck constant and f is the frequency. Substituting,
And now we can find the wavelength of the photon, which is given by
where c is the speed of light. Substituting,
Assuming the planet can be treated as a solid sphere,
(9.74 x 10^37 kg-m²) = (2/5)(5.98 x 10^24 kg)R²
R = 6.38 x 10^6 m
(9.74 x 10^37 kg-m²) = (2/5)(5.98 x 10^24 kg)R²
R = 6.38 x 10^6 m
