Answer:
1. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.
2. Refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
3. During the day the sky looks blue because it's the blue light that gets scattered the most.
4. During sunrise/sunset, rays have to travel larger distances and as red light scatters least, it is capable to reach our eyes while rest of the components are scattered away.
