X Q8. The distance between the Earth and the Sun is 1.50 * 10 to the power of 11 m.
Light takes 500 s to travel from the Sun to the Earth.
The wavelength of red light is 670 nm.
Calculate the frequency of red light, using only the data provided.

Pleas answer

increase masses, decrease separation

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
