Virtual Giants: Telescope Interferometry Quiz

The trick to building a telescope the size of a planet. Since radio waves are so large, a single dish often cannot provide sharp images. By electronically linking multiple antennas across different continents, astronomers...

Questions: 20 | Attempts: 11 | Last updated: Feb 27, 2026

Sample Question 1
In interferometry explained for Grade 11 physics, what is the primary goal of combining signals from multiple telescopes?

To make the image brighter

To increase the angular resolution

To change the color of starlight

To block out the Sun's radiation

To measure the telescope's weight

Sample Question 2
Telescope interferometry increases the light-gathering power of the system to match a single mirror the size of the entire gap.

True

False

Sample Question 3
Why are radio interferometers more common than optical ones?

Radio waves are faster than light

Radio waves have much longer wavelengths

Radio waves do not need antennas

Radio waves are always brighter

Radio waves travel through lead
