WebOct 22, 2024 · The force of gravity has a similar effect on light, where a loss in energy gives a lower frequency. Because light in a vacuum always travels at the same speed, the loss of energy and lower frequency means that the light, including the signatures of iron and silicon, shift to longer wavelengths. WebMar 27, 2013 · Gravity is important to keep satellites in orbit. Well, I guess not just important, it’s crucial – it’s what keeps the satellite in orbit. If we didn’t have gravity, the satellite wouldn’t orbit the Earth, it would just go flying off into space.
