Question

What is the source of photons that we observe from the corona?

a) Reflection of starlight
b) Synchrotron radiation
c) X-ray emission from hot gas
d) Gravitational lensing of background stars

Answer 1

The source of photons that we observe from the corona is X-ray emission from hot gas and gravitational lensing of background stars.

Step-by-step explanation:

The source of photons that we observe from the corona is

1. X-ray emission from hot gas: The corona is extremely hot, with temperatures reaching millions of degrees Celsius. This heat causes the gas in the corona to emit X-ray radiation.
2. Gravitational lensing of background stars: Gravitational lensing occurs when the gravitational field of a massive object, such as a star or galaxy, bends the path of light passing near it. In some cases, this can cause background stars to appear brighter or distorted, leading to the observation of photons from the corona.
