Eclipses of the moons of Jupiter are observed from two locations, A and B, that are about 6 months apart in Earth's orbit: Orbit of Earth Orbit of Jupiter At Point B, eclipses are observed 22 minutes later than they would have been expected based on observations at Point A. For this question, take the orbital diameter of Earth to be 3.0×1011 m.

Nature of light

Light is transverse and electromagnetic radiation that exhibits the properties of a wave as well as a particle. For this reason, light is said to have a “dual nature.”
