To calculate speed, you need to know the total distance covered
and the time it took to cover the distance.
To calculate velocity, you need the starting location, the ending location,
and the time it took to go from start to finish.
Answer:
* Larger mirrors collect more light and therefore fainter and more distant objects can have enough intensity to be detected
* arger mirrors decreases the angle of dispersion giving a better resolution of the bodies
Explanation:
Refracting telescopes get bigger every day for two main reasons.
* Larger mirrors collect more light and therefore fainter and more distant objects can have enough intensity to be detected
* the diffraction process for circular apertures is given by
θ = 1.22 λ / D
where d is the diameter of the mirror, therefore having larger mirrors decreases the angle of dispersion giving a better resolution of the bodies
Gamma rays then x rays then UVA rays then visible light then IR then radio waves (from highest to lowest frequency).
