How is sunlight made?

Answer 1

The mass discrepancy when fusing Hydrogen to Helium which is converted into energy

This much energy is produced by millions of Fusion Reactions that occur in the Sun's core every second, where hydrogen is changed into helium.

The mass of 1 hydrogen atom is about 1.00794 AMU, about four of these are fused together to form one Helium atom. The actual mass of Helium atom is about 4.0026 AMU. But if you multiply 4 hydorgen atom masses you get 4.03176. This change is mass is transformed into Energy given by #E = mc^2#.

Whereas

E stands for energy generated by a single hydrogen atom, m for mass difference or change in mass, and c for the speed of light, which is 300,000 km/sec.

m = 4.0026 - 4.03176

m is equal to 0.02916 AMU.

1 AMU = 1.660 x #10^-27# kg
m = 0.02916 x 1.660 x #10^-27#
m = 4.84 x #10^-29# kg
E = 4.84 x #10^-29# * #(300,000,000)^2#
E = 4.35 x #10^-12# joules.

The Sun has a luminosity of 3.8 x 10^26 watts.

How many of these reactions must occur in order to reach the luminosity of the sun?

n = 3.8 x #10^26# / 4.35 x #10-12#
n = 8.735 x #10^37# reactions/ sec are required to produce the Luminosity of the Sun.

Answer 2

Sunlight is produced through a process called nuclear fusion that occurs within the Sun's core. In this process, hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the form of light and heat.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
