A scientist is investigating why certain EM waves from the Sun do not reach the Earth's surface. Which property of gamma rays primarily explains their absence at ground level?
They are absorbed by upper atmosphere
Gamma rays have the shortest wavelength and the highest energy among electromagnetic waves.
Gamma rays from the Sun and space are absorbed by atoms and molecules in the upper atmosphere, so they do not reach the ground.
They do not have a long wavelength and are not stopped by clouds or reflected by the Earth's surface.
Hence, the answer is They are absorbed by upper atmosphere.
