Question

Calculate the magnitude of the faintest object that can be detected by an optical telescope of diameter 5.0 m.

Answer 1

Answer:

Generally, the space telescope can detect objects as faint as 31st magnitude...

Explanation:

the formula below:

m⋅v=mnakedeye−2+2.5⋅log10(D⋅P⋅t)

D = objective or main mirror diameter in mm

P = power or magnification

t = transmission factor, usually 0.85–0.9
