Thermonuclear reactions within the Sun's core involve the fusion of
hydrogen atoms into helium
Heat energy from the Sun's core travels to the surface mainly by way of
conducton

year

The greatest intensity of solar radiation occurs within the visible portion of
the electomagnetic spectrum
Cooler bodies like Earth mostly emit shorter wavelength radiation
compared to hotter bodies like the Sun
The hotter the body, the longer the wavelengths of maximum radiation
emitted
The intensity of radiation emitted by the Sun is the same for all
wavelengths
