Weighing Supermassive Black Holes. Which of these devices would be a better tool for measuring the masses of black holes at the centers of other galaxies: a camera that takes extremely sharp pictures or a spectrograph that produces precise measurements of emission-line wavelengths? Explain.

ANSWER:

Step 1 of 2:

 

Supermassive black holes are extremely larger black holes. The mass of the supermassive black hole is in the order of few hundreds of thousands to billions of the solar mass. We are going to find the mass of a supermassive black hole. The mass can be measured using the spectral data by the Doppler shift.
