In Atomic Spectra lab, Vernier angles (V) in degrees of a Hg-lamp has a linear dependence on wavelength (λ) in nm of line spectra: V = 0.146 λ−10.85 a) Predict the Vernier angle in degree for a line that has a wavelength of 510 nm. b) If a student found a line at a Vernier angle of 76.5°, what is the wavelength in nm of this line? - Answer- a) 63.61 b) 598.288 Best-fit line equation commonly takes "y=mx+b" format. What are y, x, m and b? - Answer- y = y-value x= x-value m = slope ...

We have learned that the centre of the milky way contains a very massive black hole. We developed this understanding by: - Monitoring the orbital motions of many individual stars in the very central parts of the Milky Way If the sun were to be squashed down small enough to become a black hole, then: - The planets in the solar system would orbit the Sun in unchanged fashion (but would receive no light from it) The first stellar mass black hole identified, Cygnus X-1, was found in 1973. The n...
