Producing larger-diameter telescopes (AQA A-Level Physics): Flashcards

$\theta \approx \frac{\lambda}{D}$

Ability to distinguish two closely spaced objects

Deform under own weight due to gravity

Array of smaller mirrors working together as one large mirror

Devices producing mechanical movement to adjust mirror segments

Computer system continuously aligning mirror segments

Separation distance between interferometer antennas

$\theta \approx \frac{\lambda}{L}$ ($L$ = baseline)

Very large baseline interferometry using intercontinental dishes

A few metres diameter
