In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
Answer:
Visible light range (between 400 and 800 nm).
Explanation:
The Sun emits a large range of electromagnetic waves, from gamma rays (higher frequencies) to radio waves (lower frequencies), through X-rays, ultraviolet rays, visible light, infrared radiation, microwaves. The peak of the Sun's energy output is actually in the visible light range (between 400 and 800 nm).
In the graph I annexed, you can see a simplified representation of the energy emissions of the Sun versus the wavelengths of those emissions. The y-axis shows the amount of energy emitted at a given wavelength and the x-axis represents different wavelengths of EM radiation. In this graph is observable than the major emission of radiation emitted by the Sun is in the visible range.
I hope you find this information useful and interesting! Good luck!
First turn 18% to a decimal, which is .18, then multiply it by 450.
450 x .18 = 81
