Which of the following are correct with regard to why the sky appears red or orange at sunset?
Choose one or more :
When the Sun is low in the sky, blue wavelengths scatter again and again, eventually reaching our eyes
Short-wavelength blue light scatters more effectively than do longer- wavelength orange or red light.
When the Sun is low in the sky at sunset, light has to travel farther through the atmosphere, so only red and orange light reach our eyes.
At sunset, light reflects off the oceans at a low angle, making the sky appear red
