Question

how is the suns radiation traveling after striking the earth? unable to figure this one out same speed as when it entered slower with a longer wavelength faster with short wavelengths

Explanation:

Sun - radiation is electromagnetic radiation. When it strikes the Earth, some is absorbed and some is reflected. The speed of electromagnetic radiation in a vacuum is constant (the speed of light). In the Earth - atmosphere system, some of the radiation is scattered and absorbed, and the re - emitted radiation (e.g., infrared radiation from the Earth's surface) has a longer wavelength due to the energy transformation and the nature of the Earth's surface and atmosphere interactions. The speed of light in a given medium is not affected by the initial striking event in a way that it speeds up or slows down in the sense described in the options other than the correct one.

Answer:

C. slower with a longer wavelength
