what is air's index of refraction?

• 2.42
• 1.33
• 1.00
• 1.5-1.75

What is the difference between reflection and refraction? 

• Both involve light bending through a medium
• Reflection is light bouncing off a medium's surface and refraction is light bending through a medium
• Reflection is light bending through a medium's surface and refraction is light bouncing off a medium
• Refraction is light being absorbed in a medium and reflection is light being bent through a different medium
